And some motors like a free 350 to replace your 305 :D
That first 400hp 383 NA had impressive torque .. great street rod/hot rod motor. Too bad there's nothing more boring than seeing a SBC in a street rod, but they look better than an LS.
You're right. The LS is an ugly engine.
All the LSoy boys are going to get man-Karen triggered if you don't get half mast over the LS
These days Chevy crate motors can be bought on the cheap compared to any other engine,of coarse a LS can make more power but the small block is king for power on a budget.
A gen one is boring, but at least the chrome kits and other dress up are equally cheap so there's little excuse for the greasy messes some leave under the hood.
Just a note to your subscibers, you don't need a wide LSA to make top end. As for torque, the 550 horse combo, made 500 ft lbs with a single plane intake, thats like trying to make torque with a wide LSA. Thanks Richard for showing that not all cam salesmen know everything is written in cement.
I'd like to see a big bang turbo 383!
I'm sure it's cheaper to go with a 400 anyway same stroke bigger bore
@@gavincarroll2553a smaller bore is better for boost. More meat on the walls
@@md_randoms2429 good point I don't think about stuff like that
24 👍's up Richard thanks again for taking us all along with you for the great show
This is one of my favorite channels!!! Go Richard!!! Great video sir
You most definitely keep us thinking. Thanks 👍
These videos are great, I'm learning so much! Thank you for your time!
Its awesome that you go back to sbc. I appreciate it!
Thanks Richard Holdener for all your hard work & knowledge. Much appreciated. U the Man.
Very welcome
I have basically the same as the first combination but with afr 195's and it's a great street motor.
Your “pops!” Has the best set up!!
That torque curve is desirable!!
Larry
Thanks for this video, it helped me determine what setup to go with!
I ❤️ this channel! You should put up a Patreon so we can kick in some cash for gas and dyno time... and subsidize your junkyard habit.
Dude idk why but I never even considered the fuel costs it would take to do all these dyno runs and often with exotic fuels. I would definitely kick in some cash or buy some merchandise!
hes taking engines that has come to his shop through the years and making spread sheets of them not running each engine on his own dime, im sure some engines have been ran on his dime but mostly customer engines at the shop he works for.... or so i suspect
and you would be wrong Corey Bell-I don't have customers
Agreed, I'd donate money to see some more specific stuff. Things like chassis dyno testing headers, exhaust systems. And the entire tuning process
@@richardholdener1727 believe me when I say... You do it because you love it and it shows! A true gear head!
Not only did you turn up the boost, you turned up the cubes. Great video as always, really enjoyed the selection of engines you picked for this video.
Just watched the fastest car episode..... Amazing and sad story. Daphne was an awesome woman. My condolences to Chad.
thnx-she was good people-the whole family
I've been a SBC guy since I was a kid, 50+ years ago. I put Chevy's hottest Corvette cam in my mom's 1968 Malibu 305 when I was in high school. A 1970-1/2 Z/28 was my first car. I love what you're doing, Richard! Oh, and that's Netflix, Fastest Car, Season 2, Episode 2, BTW. It was crazy to see you two-wheeling around out at the track, Richard! Y'all check it out here: www.netflix.com/title/80190009
Loved this episode. My Dad built me a 421 sbc w forged internals , afr heads, jesel valvetrain with a comp cam 632 /632 lift 262/274 with a 114 lsa . Twin 66mm turbos blow through a csu carb dart single plane . Going in a 70 protouring nova
This gives me a good idea of the power itll put out.
How much did it end up making?
Great and informative video for us SBC people. Thanks for making one of if not the best engine combo videos I’ve ever seen 💯
Very cool video! Love my small blocks.
Yes the key is what rpm range are you operating. You can build a 450 HP SBC then add a roots or pro charger. Adjust the boost to your liking as long as the operating range of your camshaft along with the timing permits it. 5, 6, 7, hundred horse along with a good set of heads. Fun to watch Richard Keep Dyno testing.
Yessir Richard... Sbc power is still some of the best power Around 💪🏾💪🏻💪🏾💪🏻💪🏾💪🏻💪🏾
You make some really good videos man i watch every one that i come across and it's very interesting my friend
Glad you like them!
Another Great video.....Keep them coming!
You are my RUclips King !!
My favorite so far! Still anxious to see L67 big bang
Thanks Richard, these SBC/multiple combo are great (my little 358ci, 12+ to one comp.,.600" lift solid roller, ported heads/matching intake, 750hp dp), it seems about in the middle of this stuff (n/a), feelin' confident it makes 500hp/ish----------KEEP THE SBC STUFF COMIN'!
Hey Richard..... PLEASE do one of these on an 80's/90's Volvo 4 cylinder!!! The educational value of your videos is off the charts, Thank you!!
not sure how we hook that to the dyno-I would need a car
@@richardholdener1727 So in other words, I buy an older stock Volvo with a turbo and drive it out to you so you can dyno it, upgrade it with no cost to me, dyno it again and then I drive it back home having a lot more fun than I did on the way out?!?!? Now THAT sounds like a plan Lol!!
This will be another good one 😎🐿🐿🐿🐿
Awesome vid! A while back you tested a 350/350hp Chevy small block that made over 350hp on your dyno. How about a manifold comparison of the stock Q-Jet cast iron manifold, an LT1 manifold and today`s Edelbrock RPM Air-Gap manifold on a 350/350hp spec engine to see how much hp the manifolds are worth? And then try all three manifolds with a 327/365 cam and then one of today`s Comp cams to show the bigger manifolds potential. I would love to see the results! Thanks for your hard work..
Nice video as usual Richard it would be nice to see a big bang 350 💥💥
Great video
I still haven't moved from SBC. After the 4L80e buckled on like stock, it still makes more sense to two-engine-program with SBC than to move to LS yet.
Hey Richard gotta say love the channel I watch every video, and I’d love to see you do a video to find the max hp potential of sbc vortec heads
they flow enough to support over 400 hp na
Very interesting the torque and horsepower levels on different combos variated a lot. But I'm trying to work 700ft pounds to horsepower for my transmissions roughly on my 5.7 liter ls
The SBC dyno run I would love to see is one with the Moser DOHC 32 valve conversion. It was developed by Richard Moser of Moser Engine Corp and Harvey Crane Jr. in the late 60's/early 70's. Tom McMullen had one in his second roadster and you can see it on the cover of the September 1976 Street Rodder.
EDIT: August 1971 Hot Rod had a real good image of a Moser DOHC SBC on the cover
Awesome I've learned a lot watching 💥🦍🏁👍
Big bang turbo gen 1 sbc love to see it
election is every where... so binge watching your videos. love the content
good idea
Im a middle kind of guy. 383-406 AFR 195s and a single plane with 10.5 1 on pump 92 a mid high 240s .600 lift split duration cam
I would like to see a test done on headers. Ceramic coating vs plane headers. Is there a difference in temp in the turbo housing , the intake charge ? Will the boost be affected ect. The info that you provide is the best bar none and has helped me greatly in planning my BBF twin build. Thanks
Ya good stuff
Would love to see a comparison of SBC 383, a stroked LS383 and a 6.2 to see the impact variations in stroke & bore have on engines with the effectively the same displacement. In theory the stroked LS, being ever-so-slightly under-square should have a torque advantage whereas the SBC 383 & 6.2 being over-square should have the edge on horsepower. But I would love to see how it plays out in reality!
same displacement (with same heads, cam, intake and compression)= same power almost regardless of bore and stroke (until airflow with bigger bore comes into play)
I would love to see you work with the Toyota/Lexus UZ v8s. 1uz is such a popular motor.
HANDS Holdener! 👐
So much yes.
What ignition control are you using with the distributor in the boosted applications?
Hi Richard, I need about 550hp for a drag class , im worried about my 2 bolt main SBC block and cap walk,was your block a 4 bolt for that hp and whats the max safe hp of a gen1 iron 383 build? cheers Brett
Thanks for the video Richard, I was wondering if you'd be able to make a video on how much boost you're able to run using 91 octane pump gas and straight water injection, I see everywhere about straight methanol or 50/50 or windshield washer fluid but never just pure distilled water. Im kinda curious because in the diesel world sometimes we run high 30% water injection to keep egt's down on our high power semi trucks, I'm curious as to how it would suppress detonation on a boosted gas engine, yes water isnt combustible but you figure with each pound of boost youre adding more fuel, i feel like mixing 15% or so water would suppress detonation up to any boost level youre able to run. It's a huge controversy online but there's absolutely no videos on max boost using straight water injection and how well it suppresses detonation
Content from Richard Holdener gets automatic thumbs up, comment and share
yes-that should be a rule!
Lol I run that same Crane came.It’s A BEAST! on the 406.
I love these videos, where else can a person go to get all this info in a single video? Nowhere but here from what I've seen! And were just talking this video, not to mention the hundreds of other topics and tests covered!!! If your not subscribed then whats wrong with you 😂
Right on
If you haven't already, it would be great to see an "other guys" video on the 80's/90's TBI SBC. As you know these motors are notorious for being low power and terrible flowing. It would be nice to see what can actually be done with one of these as they are soo very common. They also have a good following, but no one has really proven what they can/can't do. Plenty of people are more than eager to say "you can do this/that and make a ton of power" As I said though, no one has shown it being done. Show us if these engines are just trash like most of us believe them to be, or can they be good? Can we actually make some power with the stock TBI? Can we actually use the junk heads that come on them? I think the 5.7 TBI was rated at 195hp, can we do some minor tweaks and get mid 200? Low 300? I believe these to be the true "budget" small block as no one really wants them so in turn they are plentiful and cheap!
the stock TBI does eventually limit power -with both fuel and air flow. the intake is not good-a simple 4-barrel induction adds 30+ hp. The rest of the motor is just SBC-meaning good with lots of potential (BTW-the stock ECU is also somewhat limiting in terms of processing speed)
It's a bit ridiculous how easy it is to make 1000+ hp nowadays! And most people can't even handle and use half of it... Hench why it's equally easy to find wrecked 'Hellcat' and ZL-1 engines!
What was the cam specs on the 350 with twin 76mm turbos
I'm currently putting together a single CXRacing turbo kit with a single dual ball bearing 76 mm Turbo on a 355, 9.5 - 1 compression motor.. 224/234 duration, .525/.540 lift, 118 center flat tap hydraulic cam
I have a 406cu/in , forged rotating assembly,10.5/1cr, .548 lift hydraulic roller grind, 1.6scorpion rockers,victor jr, FST billet extreme carb,AFR 210 eliminator heads and I am wondering what you think the numbers should be? It made 526hp 504 tq which is ok until you build engines with less of everything and make comparable numbers. Local race shop built it and they are not a fly by night operation. Any response or input would be helpful. Thank you
I would like to see a dyno sweep start at 1500 rpm all the way to whatever the dyno will allow.
no one is ever at 1500 rpm at WOT
Am still waiting on full tilt sbc, something in the 650 to 700 hp range n/a. More head, cam, compression and rpm, maybe tunnel ram??? After you get there maybe throw some nitrous in the mix for us traditional folks and shoot for 1000 to 1100 hp range.
I love your videos! very cool content!
Richard would you dyno test some production sbc stuff? like old camel hump castings? i would like to see some 305 H.O headed 350's..... you know some cheap cheap combos. thanks
That's what I'm saying I got a 383 10 to 1 compression flat tops with a 280 competition Magnum cam Invicta scorpion single plane intake with 800 double Holley carburetor with some 194 valve double hump stock 64cc stock heads pumper and I've ran some 11:0's through the quarter in my 3200 lb 72 Nova with the Powerglide 3400+ stall converter and wish I knew what the horsepower and torque rating was......
look at the 302, 327 and 350 videos
@@richardholdener1727 thanks ive already seen them. but how bout some 305 headed 350's? that's a thing that goes on for 40 years now and nobody tested them on the dyno. the saying goes that the 416 and 601 casting 305 ho heads are the poor mans vortec head..
I'd like to see a 383 stroker with a comp xr294hr cam if your up for it. Doing a build for my truck and kinda wanna see what it would make at the crank
Hi Richard. Sbc is a contender to the bbc, but to not forget the ls lm7 to the 6.2 is the same contenders in a different way to displacement. Lol 😂. (I think) 1k hp. Outta old school style 350. Well,built to a 383. Need some old school to keep the youngins in awe and respect
Some of us youngs still have nothin but love with the ole gen 1 SBC's. I've got two 350s a 383 and a 400. Very great motors....soooooo easy to wrench on.
chase webber. I hear ya. I guess my point was(if I failed to be clear) the younger gen has a fascination with the ls engines because of their capabilities. They might often not know what came before this great new ugly ass motors now. The old school has class and it’s own bling. Thinking of putting old school valve covers on my 5.3 just to have that nostalgic.
I hear all sorts of theories on 2 bolt vs 4 bolt and 1 piece vs 2 piece and early vs late sbc strength and power capacity. I'd really like to see what a stock block 350 with a basic forged rotating assembly is capable of. Add boost to a 350 with forged bottom end, aluminum heads, and shoot for 800-1000 horse.
we might get 1,000 hp with the stock bottom end and ring gap
I have a production gm block in my camaro w/ billet splayed main caps and arp studs installed , scat forged crank , eagle H beam rods w/ arp bolt upgrade ,diamond pistons w/ tool steel pins . Brodix track 1 heads i hand ported and brodix single plane intake , holley 950 blow thru carb . 385”sbc w/F1R procharger , 11.75:1 compression spinning blower past max recomended speed . Car runs 8.6x @ 160mph at 3850lbs . Car is making over 1150 hp w/ a gen 1 sbc and has been together for over 10years now . Some street use , mostly track . Slowest it ever was was 9.50’s the first year out , been in mid-upper 8’s for last 4 yrs . Put about 4-500 miles on each year for last 4 years too . Tons of street pulls given people rides and even more passes at track . Been hard on it , but take care of it and paid attention to all the details during initial machining and assembly and it has treated me VERY well over the years and been extremely reliable . Freshened it up in 2016 , was built originally in 2005 , still alive and healthy today . When it did get freshened up , everything looked decent considering the years of abuse . Original build had srp pistons , big solid roller cam . 1 lifter started going bad and i caught it when i inspected my oil filter after a race . Had lifters rebuilt and replaced 2 of them , installed new pac valve springs , and custom diamond pistons w/ total seal ap rings and bumped up compression from 9:1 to 11.75:1 when freshened up in 2016 . Goes faster every season !
Would love the info on a 900hp build with a blower of some sort
I'm having problems finding a good piston for turbo on a stock stroke 350 build I want power for a good everyday drive
So at what point do the factory SBC blocks start giving up from power? 1500?
Depends mostly how far you bore out the cylinders while getting to 1,500 and partly on how you decide to get to 1,500. If you are taking a older take-out SBC or a newer casting the failure points will be vastly different depending on casting techniques. You could also treat or sleeve the block and change the theoretical failure point. And is the engine build designed to last several prolonged runs, or are we just looking for something to run for 7 or 8 seconds a few times? Durability on a factory SBC is sort of perception and choice. For my style, a newer pure factory block in most application makes me nervous around 650hp. Sure you could push it much further, but if you do, you have to keep a close eye on the internals.
Hey Richard, I love your channel!! I wanted to ask you if you have ever ran a lq4 with 317 heads? I have this combo in my truck now. I plan to up grade to 862 heads and a sloppy stage 2 cam. I wanted to know what the dyno charts would look like.
the LQ4 comes with 317 heads-so yes i have
800hp is all I need for my 1966 C10 Stepside
Is 421 a good sbc build with 245 Afr npp heads ???
Good times
One day I would like to see a wild combo built 434cid SBC with top of the line parts with an aftermarket block a set of top of the line 18 degree aluminum heads with shaft roller tip rockers, billet crankshaft, aluminum rods, 2618 forged pistons, and a Super Victor intake or another top of the line intake with a big single or twin turbos ran and controlled by Holley Dominator EFI and then after you get the best HP and TQ numbers you can from the 434cid bump it up to 440cid because to be honest I would love to see a SBC pushing out 2000+HP I know it can be done and I know it can be done with an LS,LT, and SB2
that can be done with a sbc very easy
The 383 that you did for your step dad were the heads 180cc intake and did you use 1.5 or 1.6 rockers?
Also would vortec heads work on that combination?
1.5
Please do a dyno test of a turbo engine with and without a velocity stack on the turbo air inlet.
it helps flow-especially near the flow limit of the compressor
Ever done any circle track engines? Currently working on coming up with a Good combination for a open wheel class. Rules are: any un-ported steel head, holley 2bbl carb, solid flat tappet cam, no more than 362ci sbc
did a little of that
Richard Holdener Any tips or tricks I could use? Haha
One day can you do a comparison on a Wild built combo of a BBC with a top of the line CNC match ported heads to the intake against a match ported heads to a sheet metal intake and top the engine off with a 1200+cfm billet Dominator carburetor vs a split Dominator carburetor just as long as they are similar in cfm
Quick question. For the 400 ci motor with the pro charger supercharger that created 800+ hp, what kind of intake did you guy use? Did BP provide the intake as well or was it something you guys had laying around and what’s the brand name of it. I’m trying to mock that exact setup. Separate from that setup have you used the weiand 177 supercharger before? If you have do you think it would produce the same amount of horses?
single plane victor jr or super victor-the 177 won't make nearly as much as the 6/71 or 8/71 or procharger

@@richardholdener1727 what size trans would hold up with the kind of power I’m going for??
Richard if I'm running forged internals and quality parts, will a boosted 400 make 800hp in a 4000lb vehicle reliably? Or could I turn the boost up and it still be reliable since I have forged rotating assy? Thanks, you the man!
800 hp with a boosted 408 should be easy and reliable

Thanks, maybe someday
Is there a instructional video on how you carb an LS or other fuel injection engine??🤔
I'll be quiet now and learn some more stuff.
How about a BBC 632 ci soon? THANKS
Whats the Gm goodwrench stock bottom end puke point. Lol
About 6000 rpm. Or 600hp.
I have a 1972 Corvette 350 motor which is just a 2 bolt main. Can I make up to 400 hp with a 2 bolt main or is it to much power for that motor? It is original to my corvette but not near enough power. Also if I can make up to 400hp or even 375hp I cant find anywhere to what parts I need to do so starting from the crank up. Do I use a different crank, cam, pistons ect? Just don't know what I need. Do you have anything that might show mw what to buy? Thanks
You can easily make 600hp using a 2 bolt block, no problem. For your 400hp combo, you can use the stock crank and rods. I'd personally go with a set of forged pistons, but cast pistons will easily make 400hp no problem. If you ever plan any NOS, go with forged pistons and get the ring gap right. A set of Vortec heads or even old fuelie heads with a 3 angle valve job will again, easily make 400hp, nothing special needed. You can run a hydraulic or solid lifter camshaft, I'd look for something in the .480-.525 lift range, maybe a 230-240 duration @0.050 and an 110LSA. Flat top pistons, shoot for 10.25:1 compression so you can stay on pump gas. Edelbrock Performer RPM intake and a Holly 650 to 750 cfm carb should do it for you. Just look around, there are about 10,000 different little combos like this that will make you 400hp, using pretty much factory stock parts. Have fun.
Thank You
Hey Richard, love the channel
I have one for you. I do auto cross racing in a 1984 Corvette. It is carbureted and has very small heads. I use a 650 Holly. It has a Doug Nash 4+3 manual and a Dana 44 rear end I want to build a motor. Should I simply throw heads in a cam on this motor? Not sure how much torque I would lose. Do I build a 383 or do I build a 400 small block. I can pick up at fresh tested small block for about $1500. Not sure what to do.
a bigger motor will make more torque if that is what you want. the smaller heads likely don't make more torque or power than bigger but better heads (like AFR)
The crank will be the last to break.
I have a question, if you reuse the stock gen 4 ls rods crank and pistons but put arp everything, and replace everything else plus add ring gap with lots of head work, would you consider that a modified engine or a built engine???
you are searching for something here-just ask the question you really want the answer to
@@richardholdener1727 Would you consider it a built or modified motor if you reuse the Rotating assembly after complete tear down.
Richard, I have a 358 SBC with 10.1 comp after market ported Vortec heads with 202 intake valves and stock exhaust and Pro form 1.6 rocker & screw in studs. running a Nitrous Express 50 to 275 shot kit, Keith Black Nos or boost pistons.
A 750 Qft Quick Fuel carb and single pattern, single duration 492 crane cam. With Summit’s low rise intake single plane intake. Do you have any videos with something similar on the dyno? We did dyno the motor only on pump gas years ago made something like 460hp with 478tq but never with Nos and E85 carb equipped now.
Thank you for your time. 1978 Malibu Classic Landau.
IT MADE MORE TORQUE THAN HP WITH A SINGLE PLANE?
Damn right
Hey Richard, I’m running a 350sbc with twin 76’s. Currently a comp 12-704-8 with 1.6 rockers. Jr victor with sniper 1250. Pretty sure my current heads are too small, running what I believe are some iron world s/r pro heads. What size heads would you run with this combination?
Thank you!
look for alum heads-195 afrs or tfs or even the off shore brands
Thank you!
If I have a lq9 with ls3 heads and a cam (don’t know what cam yet) fast 102 intake with a Vortech supercharger what horsepower do you think I’ll make??
with an unknown cam and unknown supercharger model and unknown boost? Very difficult to say-but I do have plenty of blower LS videos up for you to check those power levels
I'm just looking to keep my hp. & tq . For my l77 364 cid. fuel injection stock intake & not break the drivetrain.
550 to 600 hp. I think is possible. Just on a freshen up on the stock set up with cam choice of about 223 and 223 duration with a 118 lsa. Is there a good program out there to build a engine and test it ?
Be safe !
600 hp from a 6.0L takes a lot more cam and ported heads and a good intake etc...
Im new to racing so, this is very informative for my first build and bracket racing! Is it a bad item to start off with 1,000 hp?
you can always turn the boost down

no

Do you have any build sheet on a 700-800 hp 400 sbc motor ?
boosted?
What do you think of the 14° heads for the sbc. I'm looking at a 383 with the Pro action 14°heads and Crawler head kit.
the altered valve angle heads improve flow and power

Which combination would run best (im running fitech as well)
what cam and what are you doing with it-drag race?
I dnt remember the specs but its the cam that comes with the motor. I just ordered it havent received it on delivery yet.
