What an awesome narrator! An honest view that ecos the enigma of these heads that made hot rodders think and look twice. This is like listening Orsen wells ! The background music is awesome, a perfect fit . I hope he does a narration on the Ford 351 4V
Trick flow now has double hump heads in aluminum for that Nostalgia old school look but with all the Trick Flow magic fir those 600 lift cams for around $1200 a set...
I've got the 1969 double hump heads with accessory bolt holes on a 383 sitting in my 72 Nova for the old school nostalgia look even with the Victor scorpion intake
Very true man. These things had their place, but like you said time has marched on. I have a couple of them, and people still want them, but its easier on the wallet to sell them to buy the ones I want.
Have a nice pair of the same casting 68 double humps myself and have turned down more money for them than they are probably worth, but growing up I always wanted a 400sbc with a pair of the old double hump head and after getting it together with a stock bottom end 400 block was amazed at the power they produced in my 83 S-10 !!! Old school is definitely still the true cool in my opinion!!!!
had a 65 327 out of a burnt down vette,i think it was rated 375 hp ,had 202 fi heads solid lift cam with 11 something compression.sinlge quad offy/tunnel ram 800 cfm holley,hooker headers ,mallory dual point distr.and some other goodies.put it in my 64 nova ss,with 411 gears and amuncie 254 low 4 spd.turned low 11s in the quarter mile in 1978,loved that car.called it the rat killer!!
I have a 66 L-79 350hp 327 stashed away now. Had one I built back in the day with a tunnelram and a huge solid roller, had it in a 69 C-10 stepside. Engine came from a totalled 66 Chevy 2 SS. I bought the whole wrecked car for $150 bucks. Also had a M-21 4spd and 4-11 12-bolt posi. Body was wasted, got wrapped around a telephone pole back in the late 60s. Car sat in the woods for 20+yrs till I dragged it out. Hell of a deal.
@@thereluctantgearhead4544 those were the days when you could buy tri5s for a$150,other cars ,& trucks dirt cheap all sorts of flavors.brings back alot of memories of So California in the 70-80 s.
Back in the day we threw a motor away if it was going to cost $500 to rebuild, and you never put stupid money in the heads that's why if you had 202's you put them on, amazing to see people spend 3 to $5,000 for their motors nowadays
V8s are becoming exotic , manufacturers have literally told the general public this , you want a car with a V8 now a days you have to be well to do and are now in the exotic car market .
Unfortunately the shits gone way up. Typical high performance built SBCs for me these days is $5000 to $8000 grand for parts & machine work. Bigblock Chevys are $8000 to $12,000 grand. And those prices ain't bad for today's economy. Olds, Buick, & Pontiac cost even more for a real powerful build. Pontiacs are what I started with, but I can't afford them hardly anymore. I miss the good ole days.
I'm building 3 bigblock Chevys now, I'll have around $30,000 in the 3 of them. But they will all be 700+ to 800+ NA HP each. I can still build a 300hp 350 for less than 2 grand tho. Probably could build a 400hp 350 with a Vortec longblock for 2 grand. Basic 350 SBCs are still the cheapest engine to build by far and they do respond to modifications better than most.
I have 850 dollars tied up in a set of 492 heads.Over sized springs and to boot.Ported Flowed .7/16 studs.Waiting for a home.Mighty nice set of heads for old school.Can't get any better.
Those are old school gold anodized Moroso valvecovers from the late 1970s. Double humps have standard old school bolt pattern. Those heads with the staggered bolt pattern came on late 50s 283 and 265s. Pretty rare.
Couldn't agree with ya more on money spent on double humps,, although I have found most aftermarket heads arenot ready to go out off the box, they require some work just to make them right, as long as I have double humps on the shelf, I will use them, I have a set of 186's which I'm getting ready to use, which I'm making the car correct on numbers matching
one of these days i would like to build a sbc with splayed valves parts are getting harder to find in WI. whats your opinion on ductile sleeves for a sbc
If it's installed right, it'll be stronger than your other cylinders. Top Fuel dragsters have a sleeve in every cylinder. I've run many blocks with sleeves without worry.
@@thereluctantgearhead4544 iv never built a sbc for racing but iv built a few sbc and ls street engines the sbc always has a big ridge and bad taper and if they changed the oil thats it. LS is just pistons the last one i built had 340k with no taper still had the cross hatch the only thing worn out was the pistons everything else was perfect even the bearings +.0012 so if i use ptfe coated skirts and ductile sleeves it should be equal to the LS longevity but with better power add splayed valves and stroke it would be one bad a$$ n/a small block send some 3ed and 4th gens home crying
All facts. I still have 3 sets. I have the machines to work them over. I would be doing them like you, for an old school rod. I have gone with modern aluminum heads "ready to go" and still put hours into getting them right. Every set needed to be lapped in because they wouldn't hold fuel. Remember guys, ready to go ain't ready to go. Still a nice set of new aluminum is the way to go.
I just had a set of 186’s heads with accessory holes redone was on a 1974 350 I had machine to .030 over would you know flow #’s on stock 186’s heads trying to pick a mild flat tappet cam
Got 186 ,s on my 91 3/4 4 wheel Dr runs great I need more camshaft to take advantage of them, they are screw in stud's and roller rockers with hard pushrods , I converted the TBI crap to HEI and Qjet 2 great power and milage ole crane blueracer cam , I really need about a 268 but I only buy Howards cams now, Thanks for sharing I'm an old motor head at 69 I've done a lot of Drag Racing 😊😊
My first build was a 283, after swapping out a 265. All I could afford were Power Pack heads. This was back in the 60's. Very few of my buddies managed to locate Double Hump heads. Even back then, people new damn well they were the shit.
Yeah it’s the holy grail when it comes to building old skool horse power I grew up building motors in the 90’s an my whole life that’s all I ever herd was “double hump 2.02 with angle plugs! That was the top shelf heads with 2.02 intake valves an the plug angled to the exhaust valve for the dome piston engines . Then you hear of the legend “SmokeyYunick” to find out he worked with GM on a lot of motors and a bunch of heads ! He said they even sent him heads that were like a “Hemi” head. He told them there was nothing wrong with the head they had. To make casting changes for what is was worth would not be good . On there pocket book or r&d time that had already done on these heads they already had. I hear or the famous “302” motor alot of people don’t know yeah Chevy had a 302 . The first time is was built an ran was 1965 Daytona Smokey Yunick” built one an won that race feb 65 ! The previous year at that same track the 426 Hemi won 1,2,3,5 place . So in turn the facts from then state the small block Chevy with double humped heads could technically beat a 426 Hemi . The basic design used by all NHRA dragsters to day . Yeah an the thing is I think I would rather go to a electric Tesla rear end in my hot rod if I had to be told “LS” . If is not 265-400 original small block Chevy . Then I’d rather go electric . The saying in always remember that I coined my self and all the old heads said they agreed was “ if you build a small block it better be a Chevy if you build a big block it better be a Hemi! That’s just the facts based on wins pound for pound inch per inch there ain’t no small block that has more wins than the small block Chevy . If it always on paper forever in our heart. Cause my dad told me when we bleed son our blood cells are not round there shaped like a Chevy bow tie! I’d say Smokey Yunick probably did more for Chevrolet than carol shelby ever did for ford . But never got the recognition he truly deserves he help Chevy with the top three Chevy small blocks of all time 327 in 62, the 302 in the 67-69 Z28’s and the 400 small block from 70-80. I don’t recall any manufacture that brung 400 cubic inches of small block to the table . 400 small block just those words would make racers crawl under rocks an wanna hide! Other than “double humped heads” that would be the first saying that really got every ones attention! I have a 327 350 HP but couldn’t find any old double humped heads I just bought a set of aluminum ones , motor doesn’t have to be “correct” for the truck I’m putting it in . One hell of a video hats off lot of memory lane stuff couldn’t ask for a better interpretation of what they are . I seen a comment about a famous country singer building Chevy small blocks . I thought that was pretty cool this guy does sound like ol Kris ! He does know exactly what he’s talkin about. Love the video, gear heads will be gear heads when there laying in there coffin . Because right around the corner or right out side they will be be . Some guys saying do you remember that car or that motor . Even after the coffin has been lowered into the ground . It will be said I got this part or that part from him or her. Or they taught me this trick or what parts to use and what not to and such! Gear heads for life and even after !
The only head to have the angled spark plugs was the 492 and the reason it was superior to regular castings was the fact that the angled drilling of the spark plugs holes repositioned the firing end of the plugs higher in the combustion chamber so the flame wasn't blocked by the piston dome, but this was only good if you were using high dome pistons, if you were not using large domed pistonscthe results wasn't that big
If you aren`t looking for numbers matching parts don`t bother looking at them. Vortec heads make 340 HP @ 5400 rpm with a dished piston on pump gas. (602 crate motor) The humps were the best of their day and it has passed.
Exactly you can make 400hp easy with Vortecs that have only had spring clearancing and screw in studs on a 355 with flat tops, modern roller cam, good intake and carb. If you work the ports and mill them for more compression and run more ci 450+hp isn't going to be too hard. Of course even cheap Aluminum 23° heads out of the box with 355+ci and the right supporting mods will make 500 pretty easy anymore.
A buddy of mine has a '74 Z28 with an L82 that the previous owner topped with "rebuilt" 186 double humps from a DZ302 or '70 LT-1. The heads bumped up compression and the car ran great at first but started losing power after a few years. Turns out the unhardened valve seats were slowly getting beat to death without leaded fuel. He was looking at $1500+ to rebuild the heads with hardened seats and probably guides until I talked him into a set of L31 Vortec's. We found a low mileage set at a JY for $200 and after having them surfaced I lapped the valves and slapped them back together with new Viton seals. The car ran better than ever and we actually had to up the carb jetting. It's hard to beat an extra 35cfm for under $400 and I didn't even have to listen to a grinder for 10 hours to get it. I've built strong motors with double humps in the past but like you said, after 50 years they're probably gonna need a lot of work and that's gonna cost. That's also assuming you can find a rebuildable pair of castings.
I just pulled my 291 heads off the 68 327 and had the valves changed to 2.02/1.60 with hardened exhaust seats and put in screw in studs with guide plates. Cost me 600 bucks in total.
Pretty good deal. You must have a reasonable machine shop available. They all went crazy on the prices around here in the past few years. Cheaper for me to just buy a new pair of heads.
It's a local shop that has been there for about 35 years or so. It's been the same owner and is always fair with pricing and loves to talk about old engines he's done and mistakes learned over the years. For the price you mentioned would be hot tanking heads and block, pressure testing, magnaflux, honing bores reseating new cam bearing and freeze plugs. Along with machining down the heads for guide plates and threaded studs and new sized valves, valves, guides, and springs included. Well it's around the 1200 side of it. There are still some older shops that just love working on them. And most machines have made their money back over the years.
@@thereluctantgearhead4544 I believe it's the newer shops that will try and stick you much as possible as they're trying to payback the money they spent on all the new machines still.
@@orbit4367 Problem is around here is most all the competition went out of business, so the couple that survived think they can just charge whatever they want, because they are the only game in town. Gotta drive 40 miles to the next one and it's not much different. And then there's the "big name" machine shop that thinks they're the best in the world and charge accordingly since they only do racing engines. $1000 dollar valvejobs and shit. They are good, but damn. And they have a 6 month waiting list.
I have a set 492 casting with accessory holes already been to machine shop got valves and springs in them and threaded ready for studs id sell for $800- $1000
It’s not worth the investment when an off the shelf aluminum heads will destroy the old camel heads. They’re good for a restoration project and cool factor !
I dig super stock production and had my nose in more than a few. They really take an ass whopping every single run. Those pups are stretched so far beyond the intended limits it's amazing they ever survive a round. The blue print work and xraying chit is just off the chain in expenses. Like a damn boat, a hole in water you can't fill up! Camel backs sell :) Got a set of 65' vette heads sitting here to move along at some point.
Yep, pretty amazing what NHRA Stock & Superstock engines are doing with the parts they are doing it with. I grew up around that shit and Modified and Super Modified class cars. Definitely a heavy influence on how I do things. Built a 68 295hp 350 Superstock engine years ago, it made over 560hp. Also built a "Stock" L-69 305 that made almost 400hp, ran high 11s in a Malibu wagon.. Several Oldsmobile 455 Stockers in Cutlass's, a 403 Stocker for a 77 Olds 98 that ran low 12s, and a Pontiac 400 for a 74 Formula firebird. Building shit like that is more of a challenge to get the desired results and still be legal. Wouldn't want to build them everyday tho. The rules have changed dramatically since I was fuckin with them. They allow alot more now than they used to. Believe approved aftermarket heads and blocks are the norm now. Back in the 70s & 80s & 90s, a Stock/Superstock engine was still built with alot of stock parts. Current day Superstock 350s are over 650hp. They also selling for $40,000-$50,000 bucks for a Patterson or Nickens engine. Shit done got real expensive. Those classes where originally low buck regular guy classes, now ya need a million dollars to go Superstock racing. And the price of a good buildable rolling chassis from the 60s/70s has gotten crazy too. The days of the $500 67 Camaros been gone for a long time. Those were the good ole days.
@@thereluctantgearhead4544 I was talking 60 to 1980 vintage classes. Atco was in my back yard one town over. I was there from the begin at Englishtown rod run when the Old Time Drags started. Infact we had seven cars camping Friday and Saturday night in the grass feild down the back entrance road. We started that meet and now it's gone. Kinda miss the old FX cars also. SS racing is a pure money game now no doubt. Wouldn't mine campaigning a altered or C gas car thought. Time and money is all I need.
@@thereluctantgearhead4544 BOP 455's are great engines early versions 360 390 hp stock, Cadillac 472 and 500 engines 375 400 hp stock is pretty damn good, i see so many aftermarket parts now, can be built easily to 650 hp, amazing that after all of these years that old technology is better than new crap! at least you can keep rebuilding the old stuff it will be around forever! unless these crazy Liberals ban gasoline ffs it sure looks like this Biden regime wants to end all fossil fuel, question is are they sure they want a Civil War.
Are jou familiar with David visard's books and clips on utube.he build an 350 sbc performer intake and w/c crab.he fited a Mike Jones cam in it and made 410 hp I thinks.ive got similar motor and I'm gone get me that cam from Mike jones
Ran a few sets over the years, on the street and track. They're restrictive compared to aftermarket heads. I liked them when they were cheap and untouched. In the end the best thing about them is the insignia on the ends. But if I got a decent set for cheap, I'd still run them.
They can be made to make good power. Not everybody needs a $5000 dollar pair of heads and 900hp. I've used more than a few of the old humps back in the day. Wasent many choices back in the old days. I'd port the shit out of them and put big valves and shit in them. Machine work used to not cost so much. I'm gonna use some 292s on a old school 70s style racing engine. They've already had alot of work done a long time ago. So they won't cost much to get in shape. Been sitting for decades. Engine gonna be a high compression 327 with a big solid roller.
I believe rhs makes the double hump in aluminum, someone does. 2 summers ago I built a 12:1 383 stroker and I ran Elgins 30 30 duntov solid with a set of 041X heads in a 81 Malibu with a g80 locker and 410 gear. I ran my buddy in his 81 Monte with a 9:1 383 and he had a Howards .565in .585ex fully roller motor with dart pro1 64cc aluminum heads. We had the same rear end setup except he had a full spool. Basically same exact car. Neither one of us could get traction both cars would spin until up around 45,50 mph. His car sounded like a pro mod drag car with that big cam. I think if we had them hooking up it would have been an extremely close race. You just can't beat the old heads for what they are. The huge difference I seen between my steel head engine and Rods aluminum head engine was the engine temperature. Major difference, we both ran electric fans and I had a much better radiator but he could literally run 15 to 20 miles in the summer time before his motor reached normal operating temp whereas mine would reach full temp in half the amount of time if not a tad less then half with the fans off. Good video
Yep, ain't gotten any cheaper either. Machine shops are expensive as hell these days. Last pair of old iron 041 heads I dropped off costed me $1200 bucks about 2yrs ago. About what a new pair of Brodix IK 200s cost.
Old skool fuelie heads were the shit back in the day! Some called them 202's, I called them fuelie's! More air and fuel, the faster you could go! Motors are just big air pumps, so you can figure it out!
He seems pretty pissed off over a set of heads. Imagine the diatribe he'd lay down if this was a transmission or something complicated ? And that's one long ass ciggy he's draggin on !! Rubber Duck
What about the Rare corvette 2.06 experimental heads? If I, remember right. On front of the heads, was a connected small double square. I, might be wrong. Been years since I, seen those heads used on a 355 Chevy, that was on a pulling tractor. That 355 ran great with those heads!!
@@shanecloyd6646 I remember something to that effect but need to check my records I have alot of information on these heads written down , they originally called them the fulie ( F I ) heads because they were intended to be used as fuel injection on early corvettes but it really never materialized , and so what GM did because they had all these castings laying around that were already made they basically decided to use them on alot of intermediate cars like impallas, caprice, ect these heads were intended for the old dog house style fuel injection Chevy made !
There was a 624 double triangle head but it was originally used on the LT1 1971/72 camero and also used on the 1971 -74 Z/28 and 73 -79 L-82 engines, this is the only double anything head I found. Of all these cast iron fulie heads the best one is the 492 castings. Now Chevy made a 292 head that was called the turbo head and this particular head was the first casting designed specifically for racing applications, the turbo name was from a turbo charged Indy engine that never happened but somehow the turbo name stuck , these heads also had angled spark plug for engines with higher domed piston , the 492 heads also had angled plugs for the same reason
I had a 406 with set of these amd had em hoghedbout. Flowed 293 cfm at 630 lift. Had a 1000cfm holley 4150 carb. Wasnin a 79 elcamino rear engine mud bod toy. Its still got a oic on bangshift site under 850horse elcamino. The engine in it was weak so i had build another one for it and finally got rid if it. Axles were fluopedbyoside down so it wouod run foward. Hilarious barn build. Thise heads were epoxied amd all because if the port work.
1st time viewer pal and I freaking love your content!!! Funny but 👍true, don't 4get the turbo 292 heads, there a killer head for 10k rpm's and will make more power at a high rpm engine but anything below .500 lift the vortec are king.but we ole timers love to build double hump heads!!! Also I hit the subscribe button!!! Come over to MoodyblueMotorsports! Thanks buddy
Thanks for checking it out man, I do miss the old days for sure. Yep, had a few pairs of them 492s over the years myself. Alot of potential in that old iron. Just takes some effort.
Had some 292s back in the day also. Ported the hell out of them. Definitely made some power on a 331ci I built with a tunnelram, twin 660s and a big solid roller with 12.5-1 compression. I revved the shit out of that engine. Started as a 1966 L-79 350hp 327. Mine made around 540hp. 8500rpm.
Yeah I have 3 sets of them and they can be ported good by a company back east call berinski they Can make them flow great but they are not cheap , they port them for certain classifications of racing, there are many companies to choose from that make great racing performance aluminum heads. AFR is probably the best of them all.
Berinski is good. Been around a long time. If I had an unlimited budget, I'd buy ALL PRO heads. Best SBC heads made. But also the most expensive. I've seen a few 1000+hp Comp Eliminator NA SBCs built with ALL PRO heads, also found on outlaw Sprint cars, they have some serious heads for the old SBC. But ya better be wealthy. Brodix also makes some monster Sprint Car heads that are massive as hell. Very expensive tho.
I've got a ported set of angle plug 492's going on my 383 and two extra sets of 291's for my Chevelle's next engine. Still look cooler than the new shit.
Them old heads are still cool. Had a couple pair of 492s back in the day. Best head you could get back in the 70s. Pretty rare now. Many a fast car was built using them old GM heads. It's just too bad the price of machine work has gone thru the roof. I have several pairs of old heads Id like to use. Brezenski says the 291s flowed the best out of the non accessory hole humps. I'm sure he would know.
@@thereluctantgearhead4544 I just starting a 85 s10 with a 350 carbed .. any advice or other videos on motor mounts or a specific oil pan? They're be no ac heat or power steering.. THANK YOU VERY MUCH
They still have a place at a lot of dirt tracks. For some reason many dirt tracks require factory iron heads but don't allow Vortec heads? I ran a Pontiac 400 with Ram Air III heads that will outflow a Vortec and they never batted an eye. I don't get the rule makers sometimes but for every other conceivable application except Pure Stock Drag racing, anything aftermarket is better.
@@superduty4556 I did not see that I had mistyped that. I am correcting it. I actually ran 1970 #12 Ram Air III heads. And I made way more torque off the curve than any of the Chev's or Ford's. There was one guy that ran a Mopar 360. 90% ran Chev's a few Ford's and of course one Pontiac. I was required to run an iron intake which isn't a bad thing and I ran an 041 cam with 1.5 rockers. I didn't 1.65 rockers because on the dirt track under a green flag the engine seldom runs below 4k rpm's. It mostly runs between 4k and 6k so I wanted durability over the last few HP. The block was a '73 out of a Catalina and I ran H beam rods and SRP forged pistons with a stock crank. 10W40 Royal Purple synthetic racing oil and never experienced any failures. Most people don't give Pontiac engines credit for having the ability to be able to compete in endurance type racing but I saw a lot of 400 SBC's lose bearings or even a rod or two. That engine is setting in the corner of my shop. They changed the max displacement to 355 for GM and 360 for Ford and Mopar a few years ago. I should build a Pontiac 350 and show them all up with it!!!
@1967davethewave 69 and 70 ram air III were the best ever offered from the factory until modern heads and lightweight blocks came out. 455 Buick was the other BPO monster.
327 punched to 339 have the crank lightened,carrillo rods,double humps ground and flowed,install rocker screw in studs,11.5 probe pistons,air gap 780 holley,isky cam and lifters,harland sharp rockers 1.6 dropped into a 55 210 fenderwell headers 4.56 gears mickey slicks,turned 10.60 all day till it got to 98 degrees,3speed trans out of a big block wagon,those were the days,10.00 cranks for replacement

Yea they are thicker , but the port design is better on a vortec.not to mention the fast burn chamber. If you want the double hump to flow like a vortec get ready to grind grind grind. But the cool factor is priceless!
I actually wouldn't do it myself I'd just have those guys at berinski racing port them for me , I know alot about these heads but compared to berinski I'm a nothing these guys know these heads frontwards backwards side ways diagonal inside out !!! No one is better then them when it come to these heads sorry about spelling their name incorrectly
@The Reluctant Gearhead You're right infact I'm thinking now having my 291's done by them and knowing me il have them do a full on port job, I already had the screw in rocker studs but Iike a dumb ass I didn't have the stud bosses machined down for guide plates , my friend did a little pocket port on them but they definitely need more, iv had them on my little 307 for many years and it really woke that lil beast up, but now I want a Dart 400 stroked 434 , im still going to leave the 307 badges on it just to f with people 🤣
Hello I just found your channel do you ever sell parts? I’m looking to buy a Sbc dart shp intake or a afr dual plane intake if you have any for sale. Also do you have any used engines for sale?
I'm pretty much a hoarder these days. Always looking for more parts to finish my projects. I used to sell parts, but it became a hassle selling on eBay.
@@thereluctantgearhead4544 yea I sold off a ton of Sbc engines years ago when we quit racing but now I’m trying to start racing again so I’m having a 388 built but the summit heads I was gonna use are too small now that we decided to go with a better bottom end. So I wish I could sell those or trade them for a better head and just pay the difference in cash. But keep in touch I have bought up several single plane intakes and dh heads and a nice Msd setup pro billet with a 6al box that I don’t need so if u ever need anything maybe we could do some trading. The next engine I’m looking into building is a sb2.2 or a 18 degree high compression Sbc. I’ve always wanted to try those two engines out and never was able to afford them til now. So if u know of any parts I’ll be needing everything. Thanks buddy have a good day
I like old heads for street use. Double humps, 882’s, Corvette / zz4 aluminum, Vortec. They work great and do just fine at the 400 hp mark without going too nuts. You just have to be able to do most of the work yourself.
Yep, they still have their place. Too bad the machine shops charge so much these days. I have a bunch of killer old iron, but it would cost a fortune to get them all ready for use. I'm in that situation now, I'm working on a 454, was trying to build it cheap with parts I have laying around. Was gonna use a pair of 820 casting 1971 Oval port heads, they were completely built back about 35yrs ago, but now they need all new guides, fresh valve job and milled again. I'm just gonna buy a new pair of budget AFR Enforcer 335cc aluminum heads bare and still have money in my pocket. I already have enough parts to build them and I can set them up. Not to mention they flow alot more air. I'll probably bowl blend them and throw them together. I wanted to use them old iron heads, but it would cost me around $1400-$1500 bucks to get them in shape. The AFR Enforcer bare pair is $1200. Already have Manley intake valves and Ferrea exhaust valves for them and all Lunati hardware to go in. Of course I gotta swap pistons too for the increased cc chambers to get the compression up. But it'll have alot more power, so it'll be worth the hassle. Can't nothing be cheap and simple anymore it seems.
Man speaks the truth back in the day you could take it to napa get em machined and have a nice engine otherwise you might as well go LS more durable lots of power
I know back in the day my brother ran a three-quarter inch race cam and a 383 cornet and we used to race the rich boys and their Porsches up to the mountains to Phoenix
Some are better than others for sure. To build a good NHRA "Stock" Eliminator engine, ya need about 20 pairs of the head ya gotta use and flow test them all till ya find the best pair. There can be a big difference in flow with 2 identical heads.
These heads came off a 68 302 MO code. Used the block and crank in the Vega. Swapped BME aluminum rods and 13.5-1 Arias pistons, lightened up the stock forged crank & knife edged the counter weights, hard chromed the journals. 288/288@.050, 680/680 lift 106 LSA Ultradyne solid roller, extremely hogged out Bowtie heads and a ported Strip Dominator intake with a 830 Annular discharge Holley on a 2-in spacer. Stahl 1 7/8 headers. 7000 stall and 6-17 gear behind it. Revved like a chainsaw. That was decades ago.
Getting the parts together now to build a 8500+rpm 66 327 L-79 . Going with aluminum rods and SRP pistons with a 4340 lightweight crank. 13-1+ compression. Going with a .650/650 lift, 284/292@.050 106 LSA Crane solid roller with ported DART 215cc runner PRO 1s from 2010, and a DART singleplane 4500 flange ported intake. It should make over 600+hp NA. Always had a soft spot for high RPM SBCs since I was heavily influenced by Modified Production & Superstock class cars as a youth. My dad drag raced in those classes back in the 70s and Gassers back in the 60s. I once built a .060 over 307 that made close to 550hp decades ago. Prepped 327 Forged crank with bearing spacers, Bowtie rods, JE pistons, 12-25-1 compression. Used Brownfield aluminum heads on it with alot of work, angle milled to 48cc chambers. Edelbrock Victor E intake & 850 Holley DP. 630/630 lift, 270/278@.050, 106 LCA Lunati solid roller. It ran mid 10s. Nothing sounds as good as a SBC turning 8000+rpm. 5-13/5-38/5.57/6-17/6-50/7-17 gears are the norm and a whole lot of RPMs on the launch s mandatory. 7000+rpm launches are a good place to start.
You’re right. Aftermarket aluminum heads will pretty much out flow any of the old cast iron heads no-matter what make. Nowadays anyone can screw together a bullet without thinking… Without Thinking!!
Yep, it's alot easier these days to build a powerful engine. Almost too many choices. Takes alot of work to make a 60yr old head match a modern aftermarket head.
@@1996slamster yep, I still like a lot of the old ways of doing things myself. I grew up around drag racing in the 70s, so that still has a heavy influence on how I do shit. Always preferred the modified classes and Superstock.
For the most part yes but not all after market aluminum heads are the same I definitely wouldn't take a set of edelbrock heads over a set of AFR. AFR are probably the best out there
I just picked up a set of 041x heads for $40… and they already have hardened seats…. I’m gonna have the shop machine drill some steam holes for me, and in a sbc 400 they will go.
@@thereluctantgearhead4544 yes I was beating Big Blocks with my 327 but broke a crankshaft in half then went to Big Block and that's all she wrote I was putting out 600 horsepower and never ever went back to small block
They were expensive back in the 80's and hard to find. Nobody would sell them. They work great in the smaller motors. Aluminum is so much lighter. Speedway makes aluminum double humps. Aluminum intake, water pump, heads and a light carb you got over a 100 lbs off the front of the car. Put the battery in the trunk too.🤤
Fuck that lol those are 365hp heads right out the factory with a dremmel and a 15 hrs into each head plus sealed power head set w stock springs you could make over 400 net
I had a pair back in the 90s and sold them like an idiot.....big power increase on basically a stock motor....u can make a 180 motor a 280 motor by a simple bolt on job.
Or use a short water pump and old style brackets. They also make low mount alternator brackets that attach to the block, and some to the water pump. I prefer using the short water pump setups in V8 S-10 swaps and Vegas too. Every little bit of clearance helps on some swaps.
When it comes to Double. hump. heads, or any old 60s Chevrolet heads. it's not so much about the speed. It's the nostalgia. They look cool. They sound. good. a hot rod is a hot rod And you can still live like back in the day. when things were good.

@@thereluctantgearhead4544 I fuckin' hear what you're sayin! Stories are better with a few fucks embellished here and there anyway. Long time subscriber, fuckin' love it!
Exactly DNT wast money on fixing double hump heads , they have aftermarket alum heads with the double humps cast on them if u are stuck on getting double humps
Yep, those are pretty cool, but they are also pretty small, around 175cc I believe. Guy better off buying a pair of 200cc BRODIX or 200cc Promaxx heads for less money and make way more power. I seen a pair of badass 245cc AFR heads that someone carved on and made them look like old doublehumps painted Chevy orange. But it was a 650+hp 406 SBC. They had a shitload of time into them. That was a few years ago. Big Bowtie singleplane intake painted orange wasent fooling anyone tho. Engine was in a 66 Chevy 2 wagon sleeper. Ran 9s NA.
@@thereluctantgearhead4544 a friend of mine was a head and manifold porter , he used to get the vortex heads from a engine exchange for one fifty , port them install a 208 intake valve flowed 280 , he was a exhaust port expert also important for street believe it or not , he would put them on a ten point five compression 350 high lift hyd roller cam , dual plane mani , n would get five hundred hp , 500 ft lbs all with a smooth idle
@@bryang9158 They have potential if a guy wants to put the time and money into them. Built a few rowdy SBCs with ported Vortec heads myself. Spent a shitload of money on them. Definitely made good power tho. Still have a killer pair on a engine sitting on a stand. It made 500+hp when it was built with a big singleplane. I swapped a big marine Mercruiser dualplane on it for use in a truck. Lost probably 20hp, picked up probably 20lbs of torque on the low end. Has a big roller cam in it. Ran like hell in a S-10 Blazer years ago. That Mercruiser intake is a killer dualplane. Looks like a Performer RPM, but better.
@@bryang9158 I have a Performer RPM intake also, it looks like shit by comparison. But those Mercruiser high rise intakes cost around $800 bucks new. I traded a Victor Jr for it. Dude didn't know what he had. They actually came on a 430hp 383 Bravo marine engine. Expensive as hell.
If you want to run cast iron heads that blow them old double humps out of the water just go get some vortec out of the scrap yard lol. Or like he said just go to evil bay and get some DNA aluminum heads and gets some good valves and valve job and it they flow more than both of them!
I have a hell of a intake collection. At least 40-50 if I layed them all out together. Alot of them are for non Chevy engines, like Oldsmobile and Pontiacs. I have 60+ engines tucked away. Over half are Chevy engines.
Vortec nice and cheap. If we are trying to stay original, I can see these. Dart heads are way better, yeah the technology smokes the double humps. Most cats I know dumped the sbc and went LS which are the new sbc.
My machinist uses a 1965 Ford tunnelport 427 FE head for a door stop. It has a wasted chamber, but highly unusual head to say the least. Seen another dude years ago use a old 1960s 8-71 blower case from a old fuel car to hold his door open.
The smallblock Chevy while an amazing motor they're starting to reach a point where it's not worth building them anymore sadly, they have dried up from the junkyards and a good set of cylinder heads that are worth giving a hoot over vortec heads will easily cost you over a thousand dollars just to stay competitive with a ratty ol 5.3 with just a small cam, so then you build a 383 stroker, over a thousand dollars in a rotating assembly then over 1000 in cylinder heads meanwhile someone else is grabbing a 6.0 putting in half the money and still making more power than the 383
That's the general perception these days, but I've seen a different story in my life. Not everybody wants to jump on the LS bandwagon. Some people prefer to keep old engines in old cars. The trouble with the LS fanboys is they try to convince everyone that the LS is the only engine that can make power. But I'm calling bullshit on that. I'm really sick of hearing about them and everytime someone talks about a traditional SBC or a bigblock, there's always that guy telling you to LS swap it. I've built plenty of LS engines at work and worked on a hell of alot more of them, I'm pretty familiar with the LS actually. And I also know it's just one choice of many. In the real world, for every one LS I see being built I also see 10 SBCs and 5 bigblocks and 20 SB Ford's and a whole lot of Mopars. Even a few Buicks and Olds and Pontiacs. People like what they like and there's usually no convincing them otherwise. LS ain't doing shit that many other engines are also doing. SBCs ain't going away anytime soon. And if a person is so fuckin poor that they can't afford to build an engine, I suggest another hobby, cause hotrods ain't cheap no matter what engine you choose. And when it comes down to it, the bigblock chevy is still king. Add boost to a built bigblock and see what ya get. Fastest street car in America has a bigblock chevy based engine. LS is way overrated to those Facebook experts. They think they can pull a junkyard engine and stick a $200 dollar turbo on it and have 1000hp. Shit don't work that way, and those boosted junkyard LS engines never last long. You can do the same thing with a bigblock and make way more power and alot more torque. I'll never jump on the LS bandwagon and many other old gearheads think the same way. That shits a millennial thing. I also don't wear skinny jeans either.....
But people can build whatever they want and I don't try to push my shit on anyone. I just know what I like. Actually I started with Pontiac, but they got too expensive to build and the parts are getting rare. SBC is the cheapest engine one can build and they can make more power than most people need. My 84 Camaro will run mid 10s in the 1/4 with a basic single 4-barrel 357ci SBC and be able to drive it everyday. I'm totally satisfied with that. If I want it faster, I have a bunch of turbo shit and bigblocks laying around. But for a cruiser, it's way faster than it needs to be. And it's extremely simple.
I don't recommend people to use Vortec heads or any other stock head. Waste of money these days. So many aftermarket heads to choose between that it just don't make good sense to dump a shitload of cash into old heads. I have seen dirt track 383s making 560hp with Vortec heads and 355s making 520hp with them. So they can be tweaked to make good power. But those were pretty rowdy high compression builds. Don Kirn built a 15-1 427ci Rodeck block ALLPRO headed single 4 barrel SBC back in the late 90s, it made 1005Hp NA with a 4150 flange 1050cfm carb. Don't see many NA LS engines making power like that. And that was 25yrs ago. The heads flowed over 450cfm. Sprint car shit. Most young bucks think every SBC is a 200-300hp engine. But people been building them for racing almost 70yrs. So there's parts available to make them do whatever ya need them to do. Shit, Rick Santos ran 372ci SBCs in a Top Alcohol dragster class back in the mid 90s, a class fuel of blown alcohol Hemis, he had the only SBC and he was kicking everybody's ass. They ended up changing the rules because of him, they took away the weight break for runny a SB engine with inline valves, so he had to run at the same weight as the Hemis. He still gave em hell, but not as bad. But that Top Alcohol 14-71 blown 372ci SBC was making over 3000+hp back in the mid 90s. I've never seen an LS making 3000+hp. I don't hate the LS engine, I hate the cult following it has and the fanboys trying to force it on everyone else. Can you imagine if the SB Mopar guys went around telling everybody that their shit is obsolete and junk and should be swapped with a SB Mopar. Shit would get annoying real quick. But it's only LS fanboys that do that shit. I've built over 1000 engines in the past 40yrs, they were all brands and types, so I've gotten a pretty good comparison first hand with many engines. What I build is a result of that experience, I've learned that power per dollar, it's hard to beat a traditional Chevy V8 engine with anything. And new parts are being developed and sold to this day. If they were that obsolete, I don't think companies would be developing brand new SBC blocks and heads.
And speaking of a 6.0, built one for a guys 55 Chevy drag car about 10-12yrs ago, costed almost $10,000 bucks to actually build it, and it made 590hp. I can build a 350 to make 590hp for half that cost. I've built 383s and 400s that made well over 600hp and still costed way less than that NA LQ9 did. I had a 388ci SBC I built for myself about 20yrs ago, it made almost 630hp NA, costed around $7000 bucks. Ain't none of them "cheap" when you build them from the crank up. Id never trust a junkyard engine in a racecar. I bought 10 SBC core engines for $1000 about a year ago. One was a 95 LT1. Most are 4-bolt 1970s blocks. Still good deals out there.
Hell yeah, it can be done. Most folks choose the easy way out these days tho. The world has gotten lazy, including myself. Back in the day I could spend 30-40 hrs grinding on a pair of heads, but these days it would be difficult for me to sit down long enough to do it. The older I get, the less work I want to do, but I still force myself to mess with this shit daily..
I have a old pair of 041s that were used on a "Econo" dragster engine from back in the 70s. Don't know what they flow, but they are pretty hogged out. Had the shit milled out of them too.
My brother gave me the Cleveland motor he took out of his mustang. I got some double humpheads to put on it. Not sure i should now your video makes alot of sense. I really want my new motor to scream alot and beat my brother. He put a jet engine in his last spring, and the chicks really dig him now. Thanks for the heads up, lol heads up (:
The Ford Cleveland has some of the best heads ever bolted to a production engine. The 4V versions flowed around 275cfm. That's better than alot of aftermarket SBC heads.
@@thereluctantgearhead4544 thanks for the info on the flow. My brother said i should get the clevland heads fixed too. I really like how aluminum heads look tho. I'll sell the double humps and the cleveland ones too. Edelbrock makes some that look cool.
I think by the sound of it you'd be way farther ahead if you'd put that pipe down and just do one thing or the other !!!!! Sounds to me like it's pretty decent shit in that bowl. It also sounds like you do know something about small and big block Chevy motors---- about as much as me I think on the subject of restoring '67-'72 Chevy/GMC 4x4's. I've bought ,sold, and body off frame restored close to 400 of them since 1979. Don't know your age but you seem to have been around the block a bit (like me) --like the old rings of a freshly cut 50-60 year old spruce tree. You shot a good video --at least a guy learned something from it , not like these fuck'in punks just burning their rear tires off their truck that their pops just bought for them. Take it easy buddy !!!!!! Jim
Pipes are wasteful. I prefer to roll em up with 1.5s. Yep, I'm a grey beard, had my hands on engines everyday since around 1981. Done built a bunch. 67-72 Chevys are my favorite bodies. Had a few of them too. Actually started with motocross bikes back in the 70s as a kid, I'd blow up my engines and nobody would fix them for me, so I had to figure it out myself. Been fuckin with shit ever since. Bought a 53 Chevy when I was 12, that's how it all started with cars. Built a 400 Pontiac engine for it. I had more than 10 cars by the time I turned 16. Old cars were cheap back then. I've had a yard full of cars my entire life, still do today. Shits definitely an addiction.
These are 291s off a 68 302 SBC. Pretty rare. I have a few sets of 283 heads on a shelf tucked away also. 520 casting "Powerpack" heads had a bump with a triangle on it.
The high performance 283s of the early 60s had the same doublehumps that came on 327s. I think the doublehumps came around 1962 and went till 1968. The 041s and 186s are considered fuelie heads too, but with accessory holes.
I would put money in double humps before I would vortec heads, they at least won't crack. I've rode in a shitload of cars with 194-150 valves on a small 350 that absolutely screamed with nothing special done to them. Those dart knock offs, promaxx and flowtec has made both vortex and double humps obsolete.
The most powerful engine I've ever seen with modified double humps made more power than the most powerful engine I've ever seen with modified Vortec heads. And I've seen thousands of SBC builds. I've seen NHRA legal Superstock L-79 327s making 600+hp with the humps. And 383 dirt track engines with Vortec heads when allowed made around 560hp. The 355s were around 530hp with Vortec heads. 295hp 68 350 NHRA legal Superstock engines made around 560-580hp with 041 heads back in the mid 80s. They make more now. They used modified 1.94/1.50 heads too. And they flowed like a motherfucker. Most people wouldn't believe the real numbers. But they would put alot of current day aftermarket aluminum heads to shame. Ran 10.50s in the 1/4 with a Q-jet on a Victor E intake 35yrs ago.
Those Promaxx heads are real good heads for the money. Same core as the Brodix IK heads, but better. Probably best deal going. The 215s flow damn near 300cfm out of the box. About $1300 will have a pair on your door step. Real nice heads.
@@thereluctantgearhead4544 I just bought a 283 that is 100% original down to the valve covers. I want to put in a solid lifter cam. 4 speed car. 1967 Chevelle.
@@terrywillis5784 A good cylinder head for a 283 is the 48cc chamber Dart 200cc runner head from a few years back & a .026 thick head gasket, need small chambers to get the compression up. Those heads used to be popular in the circle track world. A singleplane like the Strip Dominator or Super Victor intake works well on a high RPM type build, a nice 750 doublepumper carb and a big cam. Something in the 270 to 280 @.050 range, 600+ lift, and a 106 lobe separation. Use good valvetrain parts and springs, stud girdles should be used. In the bottom end, a set of lightweight domed forged pistons with thin rings and some 4340 7/16 I-beam Scat rods, the stock forged crank is good, I've had them over 9500rpm and never seen one break. Get it all balanced together, good oil pump that'll hold 80+lbs of pressure and a 7 qt pan and windage tray. ARP main studs and head studs. Throw some 4-88s or 5-13 gear in the rear and it'll be running like a beast. I've built that basic combo a few times already and they'll make over 450-500hp no problem. Pretty high RPM type build. They sound mean as hell too. 283s can make some power, but ya gotta turn em up. In a lightweight well setup car, you could run in the 10s in the 1/4 with a engine like that. I used to bore them .125 over to a 4 inch bore, never had a problem. Them old 283 blocks are thick, probably the thickest SBC GM ever built. I had a 71 Vega I raced years ago, had a 302 in it that ran 6.20s in the 8th. Turned it 9800rpm, used a 7000 stall converter in a manual T400 with a brake and a 6-17 geared Dana 60 rear. It was loud as hell, quick too. Definitely a whole different experience than most SBC builds. I used a tunnel ram and twin 660 center squirter Holleys. Also used BME aluminum rods & Arias pistons in it and added splayed caps to the block. Still had a stock forged 3 inch stroke GM crank in it. But it was heavily modified. Alot of metal removed, deburred and knife edged, used heavily modified GM Phase 2 Bowtie heads on it and a .680 lift 288@.050 solid roller cam. Id like to build another one like that one day, I have a 1957 283 stashed away. My 302 was a 68 MO 302 from a Z-28.
I know where u are coming from. I stuck alot money into some 049 BB heads, bigger valves, ported, custom valves job, benched flowed and some high flow numbers. Never do it Again! Put them on a 454 with 9 to 1 compression and small hydraulic roller camshaft. Motor has no power and torque under 3500rpm and is nothing but a gas hog. High flow numbers don't mean shit. I'm going back to stock small valves and peanut port BB heads and leaving them stock. I need an engine that will tow weight and pull off idle to 4000rpm, never sees the light of day at 5K. High HP and high rpm don't impress me any.
@@thereluctantgearhead4544 ya I sure found that out. All I'm doing to a stock 454 now is run some small tube headers, very small single pattern camshaft and run some dome pistons and get the compression up to 9.5 to 1 from that low 8 to 1 with the peanut heads with a weiand peanut port intake and factory Q jet carb. Need that air velocity at low rpms or don't make any torque down low.
@@jessesyfie7244 That should make some torque, I'd expect at least 525lbs of torque, probably 400hp range with that combo. Be all done by 5000 grand. An old Comp Cam 268 High Energy cam is good for alot of torque in a 454.

3-5000k is a short block now. No heads, no nothing up top. Some crate engines are well over 10K now. Better go check your numbers again.
Unfortunately the shits gone way up. Typical high performance built SBCs for me these days is $5000 to $8000 grand for parts & machine work. Bigblock Chevys are $8000 to $12,000 grand. And those prices ain't bad for today's economy. Olds, Buick, & Pontiac cost even more for a real powerful build. Pontiacs are what I started with, but I can't afford them hardly anymore. I miss the good ole days.
I'm building 3 bigblock Chevys now, I'll have around $30,000 in the 3 of them. But they will all be 700+ to 800+ NA HP each. I can still build a 300hp 350 for less than 2 grand tho. Probably could build a 400hp 350 with a Vortec longblock for 2 grand. Basic 350 SBCs are still the cheapest engine to build by far and they do respond to modifications better than most.

If it's installed right, it'll be stronger than your other cylinders. Top Fuel dragsters have a sleeve in every cylinder. I've run many blocks with sleeves without worry.
@@thereluctantgearhead4544 iv never built a sbc for racing but iv built a few sbc and ls street engines the sbc always has a big ridge and bad taper and if they changed the oil thats it. LS is just pistons the last one i built had 340k with no taper still had the cross hatch the only thing worn out was the pistons everything else was perfect even the bearings +.0012 so if i use ptfe coated skirts and ductile sleeves it should be equal to the LS longevity but with better power add splayed valves and stroke it would be one bad a$$ n/a small block send some 3ed and 4th gens home crying
Nice engine 🎉 nice thoughts 🎉❤ good work 🎉
Them mountain man of the sbc lol. Love the content and education 👍
All facts. I still have 3 sets. I have the machines to work them over. I would be doing them like you, for an old school rod. I have gone with modern aluminum heads "ready to go" and still put hours into getting them right. Every set needed to be lapped in because they wouldn't hold fuel. Remember guys, ready to go ain't ready to go. Still a nice set of new aluminum is the way to go.
Right on
I just had a set of 186’s heads with accessory holes redone was on a 1974 350 I had machine to .030 over would you know flow #’s on stock 186’s heads trying to pick a mild flat tappet cam
Most 041/186 heads flowed in the 210-215cfm range.
Get a cam with a tight lobe separation. 106 or 108 will help your program along.
Got 186 ,s on my 91 3/4 4 wheel Dr runs great I need more camshaft to take advantage of them, they are screw in stud's and roller rockers with hard pushrods , I converted the TBI crap to HEI and Qjet 2 great power and milage ole crane blueracer cam , I really need about a 268 but I only buy Howards cams now, Thanks for sharing I'm an old motor head at 69 I've done a lot of Drag Racing 😊😊
My first build was a 283, after swapping out a 265. All I could afford were Power Pack heads. This was back in the 60's. Very few of my buddies managed to locate Double Hump heads. Even back then, people new damn well they were the shit.
I still have a pair of them old Powerpack heads. 520 casting I believe. Work good on 305s with alittle work.
Built a few rowdy 283s back in the day myself. Had to rev the piss out of them. Fun little engines to mess with tho.
Yeah it’s the holy grail when it comes to building old skool horse power I grew up building motors in the 90’s an my whole life that’s all I ever herd was “double hump 2.02 with angle plugs! That was the top shelf heads with 2.02 intake valves an the plug angled to the exhaust valve for the dome piston engines . Then you hear of the legend “SmokeyYunick” to find out he worked with GM on a lot of motors and a bunch of heads ! He said they even sent him heads that were like a “Hemi” head. He told them there was nothing wrong with the head they had. To make casting changes for what is was worth would not be good . On there pocket book or r&d time that had already done on these heads they already had. I hear or the famous “302” motor alot of people don’t know yeah Chevy had a 302 . The first time is was built an ran was 1965 Daytona Smokey Yunick” built one an won that race feb 65 ! The previous year at that same track the 426 Hemi won 1,2,3,5 place . So in turn the facts from then state the small block Chevy with double humped heads could technically beat a 426 Hemi . The basic design used by all NHRA dragsters to day . Yeah an the thing is I think I would rather go to a electric Tesla rear end in my hot rod if I had to be told “LS” . If is not 265-400 original small block Chevy . Then I’d rather go electric . The saying in always remember that I coined my self and all the old heads said they agreed was “ if you build a small block it better be a Chevy if you build a big block it better be a Hemi! That’s just the facts based on wins pound for pound inch per inch there ain’t no small block that has more wins than the small block Chevy . If it always on paper forever in our heart. Cause my dad told me when we bleed son our blood cells are not round there shaped like a Chevy bow tie! I’d say Smokey Yunick probably did more for Chevrolet than carol shelby ever did for ford . But never got the recognition he truly deserves he help Chevy with the top three Chevy small blocks of all time 327 in 62, the 302 in the 67-69 Z28’s and the 400 small block from 70-80. I don’t recall any manufacture that brung 400 cubic inches of small block to the table . 400 small block just those words would make racers crawl under rocks an wanna hide! Other than “double humped heads” that would be the first saying that really got every ones attention! I have a 327 350 HP but couldn’t find any old double humped heads I just bought a set of aluminum ones , motor doesn’t have to be “correct” for the truck I’m putting it in . One hell of a video hats off lot of memory lane stuff couldn’t ask for a better interpretation of what they are . I seen a comment about a famous country singer building Chevy small blocks . I thought that was pretty cool this guy does sound like ol Kris ! He does know exactly what he’s talkin about. Love the video, gear heads will be gear heads when there laying in there coffin . Because right around the corner or right out side they will be be . Some guys saying do you remember that car or that motor . Even after the coffin has been lowered into the ground . It will be said I got this part or that part from him or her. Or they taught me this trick or what parts to use and what not to and such! Gear heads for life and even after !
The only head to have the angled spark plugs was the 492 and the reason it was superior to regular castings was the fact that the angled drilling of the spark plugs holes repositioned the firing end of the plugs higher in the combustion chamber so the flame wasn't blocked by the piston dome, but this was only good if you were using high dome pistons, if you were not using large domed pistonscthe results wasn't that big
The 302 was built because there was a cubic inch restriction...they didnt race in the same class as the 426 Hemi.
If you aren`t looking for numbers matching parts don`t bother looking at them. Vortec heads make 340 HP @ 5400 rpm with a dished piston on pump gas. (602 crate motor) The humps were the best of their day and it has passed.
Exactly you can make 400hp easy with Vortecs that have only had spring clearancing and screw in studs on a 355 with flat tops, modern roller cam, good intake and carb. If you work the ports and mill them for more compression and run more ci 450+hp isn't going to be too hard. Of course even cheap Aluminum 23° heads out of the box with 355+ci and the right supporting mods will make 500 pretty easy anymore.
A buddy of mine has a '74 Z28 with an L82 that the previous owner topped with "rebuilt" 186 double humps from a DZ302 or '70 LT-1. The heads bumped up compression and the car ran great at first but started losing power after a few years. Turns out the unhardened valve seats were slowly getting beat to death without leaded fuel. He was looking at $1500+ to rebuild the heads with hardened seats and probably guides until I talked him into a set of L31 Vortec's. We found a low mileage set at a JY for $200 and after having them surfaced I lapped the valves and slapped them back together with new Viton seals. The car ran better than ever and we actually had to up the carb jetting. It's hard to beat an extra 35cfm for under $400 and I didn't even have to listen to a grinder for 10 hours to get it.
I've built strong motors with double humps in the past but like you said, after 50 years they're probably gonna need a lot of work and that's gonna cost. That's also assuming you can find a rebuildable pair of castings.
Yep, hard to beat them Vortec heads. Hell of a deal really.
What year are those? I have a set of 69 Z28 with the provisions for the long water pump
These are 68. Last year of the no accessory holes. 291 castings. Came off a MO code 68 302.
Also have a pair of 292s with accessory holes, but they are over the counter GM heads from 1975. Angle plug "Turbo" heads.
If you must have double humps I would buy the Brodix aluminum double hump lookalikes and paint them up to look like an old iron head…
Yep, that would be the way to go. Was looking at those myself for a sleeper type build. Paint it all Chevy orange.
How would a pair of good used Vortec heads compare to them?
Vortec heads make more power when compared in stock form.
I just pulled my 291 heads off the 68 327 and had the valves changed to 2.02/1.60 with hardened exhaust seats and put in screw in studs with guide plates. Cost me 600 bucks in total.
Pretty good deal. You must have a reasonable machine shop available. They all went crazy on the prices around here in the past few years. Cheaper for me to just buy a new pair of heads.
Just the work you had done on your heads would be $1000-$1200 here. Not including parts.
It's a local shop that has been there for about 35 years or so. It's been the same owner and is always fair with pricing and loves to talk about old engines he's done and mistakes learned over the years. For the price you mentioned would be hot tanking heads and block, pressure testing, magnaflux, honing bores reseating new cam bearing and freeze plugs. Along with machining down the heads for guide plates and threaded studs and new sized valves, valves, guides, and springs included. Well it's around the 1200 side of it. There are still some older shops that just love working on them. And most machines have made their money back over the years.
@@thereluctantgearhead4544 I believe it's the newer shops that will try and stick you much as possible as they're trying to payback the money they spent on all the new machines still.
@@orbit4367 Problem is around here is most all the competition went out of business, so the couple that survived think they can just charge whatever they want, because they are the only game in town. Gotta drive 40 miles to the next one and it's not much different. And then there's the "big name" machine shop that thinks they're the best in the world and charge accordingly since they only do racing engines. $1000 dollar valvejobs and shit. They are good, but damn. And they have a 6 month waiting list.
I love these heads they are absolutely perfect for dirt cars
I ran a set of CRANE FIREBALL ANGLE PLUG HEADS…BACK IN THE LATE 70’S
I have a pair now. Killer old heads. Flow better than many aftermarket modern heads. Fixing to build a old school 70s type racing engine with them.
Fixing to do a video about them I guess, not many people ever heard of them. Only us old farts.
291 have more nickel in them when they pored them they are heavy an hard to port
Definitely a chunk of iron. I ported alot of iron heads back in the day, shit takes forever.
I have a set 492 casting with accessory holes already been to machine shop got valves and springs in them and threaded ready for studs id sell for $800- $1000
It’s not worth the investment when an off the shelf aluminum heads will destroy the old camel heads. They’re good for a restoration project and cool factor !
Yep, a person can spend a shitload of money on them old heads. Better to just buy new aftermarket these days.
I dig super stock production and had my nose in more than a few. They really take an ass whopping every single run. Those pups are stretched so far beyond the intended limits it's amazing they ever survive a round. The blue print work and xraying chit is just off the chain in expenses. Like a damn boat, a hole in water you can't fill up!
Camel backs sell :)
Got a set of 65' vette heads sitting here to move along at some point.
Yep, pretty amazing what NHRA Stock & Superstock engines are doing with the parts they are doing it with. I grew up around that shit and Modified and Super Modified class cars. Definitely a heavy influence on how I do things. Built a 68 295hp 350 Superstock engine years ago, it made over 560hp. Also built a "Stock" L-69 305 that made almost 400hp, ran high 11s in a Malibu wagon.. Several Oldsmobile 455 Stockers in Cutlass's, a 403 Stocker for a 77 Olds 98 that ran low 12s, and a Pontiac 400 for a 74 Formula firebird. Building shit like that is more of a challenge to get the desired results and still be legal. Wouldn't want to build them everyday tho. The rules have changed dramatically since I was fuckin with them. They allow alot more now than they used to. Believe approved aftermarket heads and blocks are the norm now. Back in the 70s & 80s & 90s, a Stock/Superstock engine was still built with alot of stock parts. Current day Superstock 350s are over 650hp. They also selling for $40,000-$50,000 bucks for a Patterson or Nickens engine. Shit done got real expensive. Those classes where originally low buck regular guy classes, now ya need a million dollars to go Superstock racing. And the price of a good buildable rolling chassis from the 60s/70s has gotten crazy too. The days of the $500 67 Camaros been gone for a long time. Those were the good ole days.
@@thereluctantgearhead4544 I was talking 60 to 1980 vintage classes. Atco was in my back yard one town over.
I was there from the begin at Englishtown rod run when the Old Time Drags started. Infact we had seven cars camping Friday and Saturday night in the grass feild down the back entrance road. We started that meet and now it's gone.
Kinda miss the old FX cars also. SS racing is a pure money game now no doubt. Wouldn't mine campaigning a altered or C gas car thought. Time and money is all I need.
@@kenmoule825 Yep, times definitely changed. These youngsters these days don't know what they missed.
@@kenmoule825 I'd like to build a C/Gas old Chevy, a 58 or 59 body would be cool.
@@thereluctantgearhead4544 BOP 455's are great engines early versions 360 390 hp stock, Cadillac 472 and 500 engines 375 400 hp stock is pretty damn good, i see so many aftermarket parts now, can be built easily to 650 hp, amazing that after all of these years that old technology is better than new crap! at least you can keep rebuilding the old stuff it will be around forever! unless these crazy Liberals ban gasoline ffs it sure looks like this Biden regime wants to end all fossil fuel, question is are they sure they want a Civil War.
Are jou familiar with David visard's books and clips on utube.he build an 350 sbc performer intake and w/c crab.he fited a Mike Jones cam in it and made 410 hp I thinks.ive got similar motor and I'm gone get me that cam from Mike jones
Yep, been reading his books since the 1970s. Lots of good info. Dude is sharp. I believe I have most of his books tucked away.
Ran a few sets over the years, on the street and track. They're restrictive compared to aftermarket heads. I liked them when they were cheap and untouched. In the end the best thing about them is the insignia on the ends. But if I got a decent set for cheap, I'd still run them.
They can be made to make good power. Not everybody needs a $5000 dollar pair of heads and 900hp. I've used more than a few of the old humps back in the day. Wasent many choices back in the old days. I'd port the shit out of them and put big valves and shit in them. Machine work used to not cost so much. I'm gonna use some 292s on a old school 70s style racing engine. They've already had alot of work done a long time ago. So they won't cost much to get in shape. Been sitting for decades. Engine gonna be a high compression 327 with a big solid roller.
Built a 327 back in the 80s that made 540hp at 7800rpm with ported 492 angle plug heads. Ran 7.00s in the 8th in a 69 C-10 pickup.
I believe rhs makes the double hump in aluminum, someone does. 2 summers ago I built a 12:1 383 stroker and I ran Elgins 30 30 duntov solid with a set of 041X heads in a 81 Malibu with a g80 locker and 410 gear. I ran my buddy in his 81 Monte with a 9:1 383 and he had a Howards .565in .585ex fully roller motor with dart pro1 64cc aluminum heads. We had the same rear end setup except he had a full spool. Basically same exact car. Neither one of us could get traction both cars would spin until up around 45,50 mph. His car sounded like a pro mod drag car with that big cam. I think if we had them hooking up it would have been an extremely close race. You just can't beat the old heads for what they are. The huge difference I seen between my steel head engine and Rods aluminum head engine was the engine temperature. Major difference, we both ran electric fans and I had a much better radiator but he could literally run 15 to 20 miles in the summer time before his motor reached normal operating temp whereas mine would reach full temp in half the amount of time if not a tad less then half with the fans off. Good video
Back in the days the double hump heads was the only fucking game in town😅Like this guy style
Last set I had redone was in 2007 and I had over $800 in machine work
Yep, ain't gotten any cheaper either. Machine shops are expensive as hell these days. Last pair of old iron 041 heads I dropped off costed me $1200 bucks about 2yrs ago. About what a new pair of Brodix IK 200s cost.
Old skool fuelie heads were the shit back in the day! Some called them 202's, I called them fuelie's! More air and fuel, the faster you could go! Motors are just big air pumps, so you can figure it out!
They bring good money to the right person looking to restore back matching dates
He seems pretty pissed off over a set of heads. Imagine the diatribe he'd lay down if this was a transmission or something complicated ? And that's one long ass ciggy he's draggin on !!
Rubber Duck
Even Back in the 80s i had a set of 461 on my 327 the guides were shot so i just bought a set world product heads pretty cheap.
What about the Rare corvette 2.06 experimental heads? If I, remember right. On front of the heads, was a connected small double square. I, might be wrong. Been years since I, seen those heads used on a 355 Chevy, that was on a pulling tractor. That 355 ran great with those heads!!
What head was that????? was it aluminum or iron???????
Iron
@@shanecloyd6646 I remember something to that effect but need to check my records I have alot of information on these heads written down , they originally called them the fulie ( F I ) heads because they were intended to be used as fuel injection on early corvettes but it really never materialized , and so what GM did because they had all these castings laying around that were already made they basically decided to use them on alot of intermediate cars like impallas, caprice, ect these heads were intended for the old dog house style fuel injection Chevy made !
There was a 624 double triangle head but it was originally used on the LT1 1971/72 camero and also used on the 1971 -74 Z/28 and 73 -79 L-82 engines, this is the only double anything head I found. Of all these cast iron fulie heads the best one is the 492 castings. Now Chevy made a 292 head that was called the turbo head and this particular head was the first casting designed specifically for racing applications, the turbo name was from a turbo charged Indy engine that never happened but somehow the turbo name stuck , these heads also had angled spark plug for engines with higher domed piston , the 492 heads also had angled plugs for the same reason
@@shanecloyd6646 the very first fulie head castings was the 461 head the last castings were the 291 head
Mine have already been done up and I'm about to put it all together I've been saving parts for 20 or more years
That old school shit is still cool, just got expensive these days. Plenty of potential in them old heads.
I like the durability of the old fashion stuff.
The fact that 55-60 year old auto parts are still in use says alot. That old shit is durable.
How fast can you afford to go
Yep, pile of money can definitely make them perform.
I had a 406 with set of these amd had em hoghedbout. Flowed 293 cfm at 630 lift. Had a 1000cfm holley 4150 carb. Wasnin a 79 elcamino rear engine mud bod toy. Its still got a oic on bangshift site under 850horse elcamino. The engine in it was weak so i had build another one for it and finally got rid if it. Axles were fluopedbyoside down so it wouod run foward. Hilarious barn build. Thise heads were epoxied amd all because if the port work.
I've seen people get big numbers out of them, just look at the NHRA Superstock 350s are doing. Definitely have potential.
@@thereluctantgearhead4544 just alot of fun man. 👍
@@richbon9904 I know that's right. Half the fun is building them.
1st time viewer pal and I freaking love your content!!! Funny but 👍true, don't 4get the turbo 292 heads, there a killer head for 10k rpm's and will make more power at a high rpm engine but anything below .500 lift the vortec are king.but we ole timers love to build double hump heads!!! Also I hit the subscribe button!!! Come over to MoodyblueMotorsports! Thanks buddy
Thanks for checking it out man, I do miss the old days for sure. Yep, had a few pairs of them 492s over the years myself. Alot of potential in that old iron. Just takes some effort.
Had some 292s back in the day also. Ported the hell out of them. Definitely made some power on a 331ci I built with a tunnelram, twin 660s and a big solid roller with 12.5-1 compression. I revved the shit out of that engine. Started as a 1966 L-79 350hp 327. Mine made around 540hp. 8500rpm.
Only way i improved mine was polishing them and was no way close to stock when i was done
I think I got stoned listening to this guy.
Yeah I have 3 sets of them and they can be ported good by a company back east call berinski they Can make them flow great but they are not cheap , they port them for certain classifications of racing, there are many companies to choose from that make great racing performance aluminum heads. AFR is probably the best of them all.
Berinski is good. Been around a long time. If I had an unlimited budget, I'd buy ALL PRO heads. Best SBC heads made. But also the most expensive. I've seen a few 1000+hp Comp Eliminator NA SBCs built with ALL PRO heads, also found on outlaw Sprint cars, they have some serious heads for the old SBC. But ya better be wealthy. Brodix also makes some monster Sprint Car heads that are massive as hell. Very expensive tho.
Patterson Racing can work some magic with the old double humps, they're Superstock engines are always top of the pack.
Back east ? Randy Brzezinski is from Wisconsin.
I've got a ported set of angle plug 492's going on my 383 and two extra sets of 291's for my Chevelle's next engine. Still look cooler than the new shit.
Them old heads are still cool. Had a couple pair of 492s back in the day. Best head you could get back in the 70s. Pretty rare now. Many a fast car was built using them old GM heads. It's just too bad the price of machine work has gone thru the roof. I have several pairs of old heads Id like to use. Brezenski says the 291s flowed the best out of the non accessory hole humps. I'm sure he would know.

Haha! Glad ya enjoyed it.
They still have a place at a lot of dirt tracks. For some reason many dirt tracks require factory iron heads but don't allow Vortec heads? I ran a Pontiac 400 with Ram Air III heads that will outflow a Vortec and they never batted an eye. I don't get the rule makers sometimes but for every other conceivable application except Pure Stock Drag racing, anything aftermarket is better.
You ran round ports on a dirt track? 😳
@@superduty4556 I did not see that I had mistyped that. I am correcting it. I actually ran 1970 #12 Ram Air III heads. And I made way more torque off the curve than any of the Chev's or Ford's. There was one guy that ran a Mopar 360. 90% ran Chev's a few Ford's and of course one Pontiac. I was required to run an iron intake which isn't a bad thing and I ran an 041 cam with 1.5 rockers. I didn't 1.65 rockers because on the dirt track under a green flag the engine seldom runs below 4k rpm's. It mostly runs between 4k and 6k so I wanted durability over the last few HP. The block was a '73 out of a Catalina and I ran H beam rods and SRP forged pistons with a stock crank. 10W40 Royal Purple synthetic racing oil and never experienced any failures. Most people don't give Pontiac engines credit for having the ability to be able to compete in endurance type racing but I saw a lot of 400 SBC's lose bearings or even a rod or two. That engine is setting in the corner of my shop. They changed the max displacement to 355 for GM and 360 for Ford and Mopar a few years ago. I should build a Pontiac 350 and show them all up with it!!!
@1967davethewave
69 and 70 ram air III were the best ever offered from the factory until modern heads and lightweight blocks came out. 455 Buick was the other BPO monster.
@@kenmoule825 I think SD heads were better than RAIII D-ports by far.

@@thereluctantgearhead4544 lighten that rotating assembly and blow by them using an extra 1000 rpm's on the big end,it worked for me,go get him hot rod
Yea they are thicker , but the port design is better on a vortec.not to mention the fast burn chamber. If you want the double hump to flow like a vortec get ready to grind grind grind. But the cool factor is priceless!
Yep, kinda what I said. But the old heads can be ported more than a Vortec.
I actually wouldn't do it myself I'd just have those guys at berinski racing port them for me , I know alot about these heads but compared to berinski I'm a nothing these guys know these heads frontwards backwards side ways diagonal inside out !!! No one is better then them when it come to these heads sorry about spelling their name incorrectly
@The Reluctant Gearhead Yes and no it all depends on what heads you are using
@@johnalarcon5006 They are definitely skilled with the early iron. Prices ain't real bad either.
@The Reluctant Gearhead You're right infact I'm thinking now having my 291's done by them and knowing me il have them do a full on port job, I already had the screw in rocker studs but Iike a dumb ass I didn't have the stud bosses machined down for guide plates , my friend did a little pocket port on them but they definitely need more, iv had them on my little 307 for many years and it really woke that lil beast up, but now I want a Dart 400 stroked 434 , im still going to leave the 307 badges on it just to f with people 🤣
I'm adopting a 327 block with 202 heads to start, I'm going to make this engine shine 😊
Damn good engines to build. You'll be happy with it. Durable as hell too.
Hello I just found your channel do you ever sell parts? I’m looking to buy a Sbc dart shp intake or a afr dual plane intake if you have any for sale. Also do you have any used engines for sale?
I'm pretty much a hoarder these days. Always looking for more parts to finish my projects. I used to sell parts, but it became a hassle selling on eBay.
@@thereluctantgearhead4544 yea I sold off a ton of Sbc engines years ago when we quit racing but now I’m trying to start racing again so I’m having a 388 built but the summit heads I was gonna use are too small now that we decided to go with a better bottom end. So I wish I could sell those or trade them for a better head and just pay the difference in cash. But keep in touch I have bought up several single plane intakes and dh heads and a nice Msd setup pro billet with a 6al box that I don’t need so if u ever need anything maybe we could do some trading. The next engine I’m looking into building is a sb2.2 or a 18 degree high compression Sbc. I’ve always wanted to try those two engines out and never was able to afford them til now. So if u know of any parts I’ll be needing everything. Thanks buddy have a good day
I have an awesome set
I like old heads for street use. Double humps, 882’s, Corvette / zz4 aluminum, Vortec.
They work great and do just fine at the 400 hp mark without going too nuts.
You just have to be able to do most of the work yourself.
Yep, they still have their place. Too bad the machine shops charge so much these days. I have a bunch of killer old iron, but it would cost a fortune to get them all ready for use. I'm in that situation now, I'm working on a 454, was trying to build it cheap with parts I have laying around. Was gonna use a pair of 820 casting 1971 Oval port heads, they were completely built back about 35yrs ago, but now they need all new guides, fresh valve job and milled again. I'm just gonna buy a new pair of budget AFR Enforcer 335cc aluminum heads bare and still have money in my pocket. I already have enough parts to build them and I can set them up. Not to mention they flow alot more air. I'll probably bowl blend them and throw them together. I wanted to use them old iron heads, but it would cost me around $1400-$1500 bucks to get them in shape. The AFR Enforcer bare pair is $1200. Already have Manley intake valves and Ferrea exhaust valves for them and all Lunati hardware to go in. Of course I gotta swap pistons too for the increased cc chambers to get the compression up. But it'll have alot more power, so it'll be worth the hassle. Can't nothing be cheap and simple anymore it seems.
882’s are garbage
Man speaks the truth back in the day you could take it to napa get em machined and have a nice engine otherwise you might as well go LS more durable lots of power
Don’t forget about the 3/4 race camshafts lmao 😂✌️😎
I always ask , what, you couldn't afford a whole race cam .... lmao !!
This actually has a beginning point. The 3/4 cam was a 750 lift at the valve on a flathead Ford.
V6 cam....
I know back in the day my brother ran a three-quarter inch race cam and a 383 cornet and we used to race the rich boys and their Porsches up to the mountains to Phoenix
It would idle at 40 miles an hour
The vortec heads I had under flowed the 462,and the 461. Know my AFR made them look them look like they where junk heads.
Some are better than others for sure. To build a good NHRA "Stock" Eliminator engine, ya need about 20 pairs of the head ya gotta use and flow test them all till ya find the best pair. There can be a big difference in flow with 2 identical heads.
Whats your opinion on a 302 Chevy?
Killer engine, I ran 6.20s in the 1/8th with a NA 302 in a Vega drag car. 9800rpm on the shifts. Wish I still had it.
These heads came off a 68 302 MO code. Used the block and crank in the Vega. Swapped BME aluminum rods and 13.5-1 Arias pistons, lightened up the stock forged crank & knife edged the counter weights, hard chromed the journals. 288/288@.050, 680/680 lift 106 LSA Ultradyne solid roller, extremely hogged out Bowtie heads and a ported Strip Dominator intake with a 830 Annular discharge Holley on a 2-in spacer. Stahl 1 7/8 headers. 7000 stall and 6-17 gear behind it. Revved like a chainsaw. That was decades ago.
Getting the parts together now to build a 8500+rpm 66 327 L-79 . Going with aluminum rods and SRP pistons with a 4340 lightweight crank. 13-1+ compression. Going with a .650/650 lift, 284/292@.050 106 LSA Crane solid roller with ported DART 215cc runner PRO 1s from 2010, and a DART singleplane 4500 flange ported intake. It should make over 600+hp NA. Always had a soft spot for high RPM SBCs since I was heavily influenced by Modified Production & Superstock class cars as a youth. My dad drag raced in those classes back in the 70s and Gassers back in the 60s. I once built a .060 over 307 that made close to 550hp decades ago. Prepped 327 Forged crank with bearing spacers, Bowtie rods, JE pistons, 12-25-1 compression. Used Brownfield aluminum heads on it with alot of work, angle milled to 48cc chambers. Edelbrock Victor E intake & 850 Holley DP. 630/630 lift, 270/278@.050, 106 LCA Lunati solid roller. It ran mid 10s. Nothing sounds as good as a SBC turning 8000+rpm. 5-13/5-38/5.57/6-17/6-50/7-17 gears are the norm and a whole lot of RPMs on the launch s mandatory. 7000+rpm launches are a good place to start.
You’re right. Aftermarket aluminum heads will pretty much out flow any of the old cast iron heads no-matter what make. Nowadays anyone can screw together a bullet without thinking… Without Thinking!!
Yep, it's alot easier these days to build a powerful engine. Almost too many choices. Takes alot of work to make a 60yr old head match a modern aftermarket head.
I prefer the work. We run a set of very modified 462’s on our Super-Gas car.
@@1996slamster yep, I still like a lot of the old ways of doing things myself. I grew up around drag racing in the 70s, so that still has a heavy influence on how I do shit. Always preferred the modified classes and Superstock.

Then you still have to drill holes for brackets on street engine
Or use a short water pump and old style brackets. They also make low mount alternator brackets that attach to the block, and some to the water pump. I prefer using the short water pump setups in V8 S-10 swaps and Vegas too. Every little bit of clearance helps on some swaps.
A lot of 350 sbc powered boats used short water pumps and have cool alternator brackets and pulleys. 70s corvettes too.
When it comes to Double. hump. heads, or any old 60s Chevrolet heads. it's not so much about the speed. It's the nostalgia. They look cool. They sound. good. a hot rod is a hot rod And you can still live like back in the day. when things were good.
Yep, that's why I'll always like them. They come from a simpler time in life. Cast iron chunks of history.

Vortec nice and cheap. If we are trying to stay original, I can see these. Dart heads are way better, yeah the technology smokes the double humps. Most cats I know dumped the sbc and went LS which are the new sbc.
Make good door stops
Haha!
My machinist uses a 1965 Ford tunnelport 427 FE head for a door stop. It has a wasted chamber, but highly unusual head to say the least. Seen another dude years ago use a old 1960s 8-71 blower case from a old fuel car to hold his door open.
The smallblock Chevy while an amazing motor they're starting to reach a point where it's not worth building them anymore sadly, they have dried up from the junkyards and a good set of cylinder heads that are worth giving a hoot over vortec heads will easily cost you over a thousand dollars just to stay competitive with a ratty ol 5.3 with just a small cam, so then you build a 383 stroker, over a thousand dollars in a rotating assembly then over 1000 in cylinder heads meanwhile someone else is grabbing a 6.0 putting in half the money and still making more power than the 383
That's the general perception these days, but I've seen a different story in my life. Not everybody wants to jump on the LS bandwagon. Some people prefer to keep old engines in old cars. The trouble with the LS fanboys is they try to convince everyone that the LS is the only engine that can make power. But I'm calling bullshit on that. I'm really sick of hearing about them and everytime someone talks about a traditional SBC or a bigblock, there's always that guy telling you to LS swap it. I've built plenty of LS engines at work and worked on a hell of alot more of them, I'm pretty familiar with the LS actually. And I also know it's just one choice of many. In the real world, for every one LS I see being built I also see 10 SBCs and 5 bigblocks and 20 SB Ford's and a whole lot of Mopars. Even a few Buicks and Olds and Pontiacs. People like what they like and there's usually no convincing them otherwise. LS ain't doing shit that many other engines are also doing. SBCs ain't going away anytime soon. And if a person is so fuckin poor that they can't afford to build an engine, I suggest another hobby, cause hotrods ain't cheap no matter what engine you choose. And when it comes down to it, the bigblock chevy is still king. Add boost to a built bigblock and see what ya get. Fastest street car in America has a bigblock chevy based engine. LS is way overrated to those Facebook experts. They think they can pull a junkyard engine and stick a $200 dollar turbo on it and have 1000hp. Shit don't work that way, and those boosted junkyard LS engines never last long. You can do the same thing with a bigblock and make way more power and alot more torque. I'll never jump on the LS bandwagon and many other old gearheads think the same way. That shits a millennial thing. I also don't wear skinny jeans either.....
But people can build whatever they want and I don't try to push my shit on anyone. I just know what I like. Actually I started with Pontiac, but they got too expensive to build and the parts are getting rare. SBC is the cheapest engine one can build and they can make more power than most people need. My 84 Camaro will run mid 10s in the 1/4 with a basic single 4-barrel 357ci SBC and be able to drive it everyday. I'm totally satisfied with that. If I want it faster, I have a bunch of turbo shit and bigblocks laying around. But for a cruiser, it's way faster than it needs to be. And it's extremely simple.
I don't recommend people to use Vortec heads or any other stock head. Waste of money these days. So many aftermarket heads to choose between that it just don't make good sense to dump a shitload of cash into old heads. I have seen dirt track 383s making 560hp with Vortec heads and 355s making 520hp with them. So they can be tweaked to make good power. But those were pretty rowdy high compression builds. Don Kirn built a 15-1 427ci Rodeck block ALLPRO headed single 4 barrel SBC back in the late 90s, it made 1005Hp NA with a 4150 flange 1050cfm carb. Don't see many NA LS engines making power like that. And that was 25yrs ago. The heads flowed over 450cfm. Sprint car shit. Most young bucks think every SBC is a 200-300hp engine. But people been building them for racing almost 70yrs. So there's parts available to make them do whatever ya need them to do. Shit, Rick Santos ran 372ci SBCs in a Top Alcohol dragster class back in the mid 90s, a class fuel of blown alcohol Hemis, he had the only SBC and he was kicking everybody's ass. They ended up changing the rules because of him, they took away the weight break for runny a SB engine with inline valves, so he had to run at the same weight as the Hemis. He still gave em hell, but not as bad. But that Top Alcohol 14-71 blown 372ci SBC was making over 3000+hp back in the mid 90s. I've never seen an LS making 3000+hp. I don't hate the LS engine, I hate the cult following it has and the fanboys trying to force it on everyone else. Can you imagine if the SB Mopar guys went around telling everybody that their shit is obsolete and junk and should be swapped with a SB Mopar. Shit would get annoying real quick. But it's only LS fanboys that do that shit. I've built over 1000 engines in the past 40yrs, they were all brands and types, so I've gotten a pretty good comparison first hand with many engines. What I build is a result of that experience, I've learned that power per dollar, it's hard to beat a traditional Chevy V8 engine with anything. And new parts are being developed and sold to this day. If they were that obsolete, I don't think companies would be developing brand new SBC blocks and heads.
And speaking of a 6.0, built one for a guys 55 Chevy drag car about 10-12yrs ago, costed almost $10,000 bucks to actually build it, and it made 590hp. I can build a 350 to make 590hp for half that cost. I've built 383s and 400s that made well over 600hp and still costed way less than that NA LQ9 did. I had a 388ci SBC I built for myself about 20yrs ago, it made almost 630hp NA, costed around $7000 bucks. Ain't none of them "cheap" when you build them from the crank up. Id never trust a junkyard engine in a racecar. I bought 10 SBC core engines for $1000 about a year ago. One was a 95 LT1. Most are 4-bolt 1970s blocks. Still good deals out there.
Damn man send me a intake off that wall for a sbc
1989 caprice classic brougham is what it put it in lol

Pipes are wasteful. I prefer to roll em up with 1.5s. Yep, I'm a grey beard, had my hands on engines everyday since around 1981. Done built a bunch. 67-72 Chevys are my favorite bodies. Had a few of them too. Actually started with motocross bikes back in the 70s as a kid, I'd blow up my engines and nobody would fix them for me, so I had to figure it out myself. Been fuckin with shit ever since. Bought a 53 Chevy when I was 12, that's how it all started with cars. Built a 400 Pontiac engine for it. I had more than 10 cars by the time I turned 16. Old cars were cheap back then. I've had a yard full of cars my entire life, still do today. Shits definitely an addiction.

Those double humps on the end of the head don't always mean anything . My dad had a few 283 2bbl engines that had those exact same humps on them .
These are 291s off a 68 302 SBC. Pretty rare. I have a few sets of 283 heads on a shelf tucked away also. 520 casting "Powerpack" heads had a bump with a triangle on it.
The high performance 283s of the early 60s had the same doublehumps that came on 327s. I think the doublehumps came around 1962 and went till 1968. The 041s and 186s are considered fuelie heads too, but with accessory holes.
I would put money in double humps before I would vortec heads, they at least won't crack. I've rode in a shitload of cars with 194-150 valves on a small 350 that absolutely screamed with nothing special done to them. Those dart knock offs, promaxx and flowtec has made both vortex and double humps obsolete.
The most powerful engine I've ever seen with modified double humps made more power than the most powerful engine I've ever seen with modified Vortec heads. And I've seen thousands of SBC builds. I've seen NHRA legal Superstock L-79 327s making 600+hp with the humps. And 383 dirt track engines with Vortec heads when allowed made around 560hp. The 355s were around 530hp with Vortec heads. 295hp 68 350 NHRA legal Superstock engines made around 560-580hp with 041 heads back in the mid 80s. They make more now. They used modified 1.94/1.50 heads too. And they flowed like a motherfucker. Most people wouldn't believe the real numbers. But they would put alot of current day aftermarket aluminum heads to shame. Ran 10.50s in the 1/4 with a Q-jet on a Victor E intake 35yrs ago.
Those Promaxx heads are real good heads for the money. Same core as the Brodix IK heads, but better. Probably best deal going. The 215s flow damn near 300cfm out of the box. About $1300 will have a pair on your door step. Real nice heads.

Those heads used to be popular in the circle track world. A singleplane like the Strip Dominator or Super Victor intake works well on a high RPM type build, a nice 750 doublepumper carb and a big cam. Something in the 270 to 280 @.050 range, 600+ lift, and a 106 lobe separation. Use good valvetrain parts and springs, stud girdles should be used. In the bottom end, a set of lightweight domed forged pistons with thin rings and some 4340 7/16 I-beam Scat rods, the stock forged crank is good, I've had them over 9500rpm and never seen one break. Get it all balanced together, good oil pump that'll hold 80+lbs of pressure and a 7 qt pan and windage tray. ARP main studs and head studs. Throw some 4-88s or 5-13 gear in the rear and it'll be running like a beast. I've built that basic combo a few times already and they'll make over 450-500hp no problem. Pretty high RPM type build. They sound mean as hell too. 283s can make some power, but ya gotta turn em up. In a lightweight well setup car, you could run in the 10s in the 1/4 with a engine like that. I used to bore them .125 over to a 4 inch bore, never had a problem. Them old 283 blocks are thick, probably the thickest SBC GM ever built. I had a 71 Vega I raced years ago, had a 302 in it that ran 6.20s in the 8th. Turned it 9800rpm, used a 7000 stall converter in a manual T400 with a brake and a 6-17 geared Dana 60 rear. It was loud as hell, quick too. Definitely a whole different experience than most SBC builds. I used a tunnel ram and twin 660 center squirter Holleys. Also used BME aluminum rods & Arias pistons in it and added splayed caps to the block. Still had a stock forged 3 inch stroke GM crank in it. But it was heavily modified. Alot of metal removed, deburred and knife edged, used heavily modified GM Phase 2 Bowtie heads on it and a .680 lift 288@.050 solid roller cam. Id like to build another one like that one day, I have a 1957 283 stashed away. My 302 was a 68 MO 302 from a Z-28.

High HP and high rpm don't impress me any.

Wow! Small world. I was born at Barksdale AFB ,and raised in Southern California. Went to school in Northern California and finally I been here in Yukon, Oklahoma for the last 10 years now.
@@sportsmansparadice42 I too was born at Barksdale AFB, during the Vietnam era. Went to Huntington High School back in the 80s. I've done alot of moving around myself over the years. Lousiana turned to shit.
@@sportsmansparadice42 Shreveport was pretty cool back in the day tho. Had alot of fun there. Used to street race at Clyde Fant park and the GM plant. Big ass parties back in the day. Big street race scene. Also used to hang out at Boothill Speedway alot. I lived right down the road from there.
