@@mustangandfrankenstein Good luck to you as well. I'm probably stroking mine to 393. I'm using a 4bbl throttle body injection system and have a digital dash so I don't have to worry about gauges and I can tune the injection from the dash
Cheaper option would be to get a cam similarly to the package one, slap an appropriate carb on it, with intake. Ebay has plenty of single plane or dual plane intakes for anywhere from 120-200$ and people have reviewed these many a time on ebay. Stiffer valve springs and 1.6:1 rockers. If you want to take it a step further get your cast heads ported. Cheap enough and still get a huge boost to factory.
@@RunningFlames I have ported D0Oe heads and even they don't compare to the aftermarket options, same goes for comparing a stock block vs a dart block or something like that. They'll get you closer but the cost difference of porting your stock heads and machining them to accept more lift isn't very far from a drop in set of aftermarkets.
It has 5,969" connecting rods, 3/8" rod bolts and 1/2" head bolts! Bolts right up where the 302 does! The block is strong enough to shoot 150 pass after pass. We shot 150 on Speed Pro cast pistons, just backed the timing back 6 degrees! Cheap, dependable fun!
@@thetriode those were designed for low RPM torque--a good tuner can get a stock 5.0 into the mid 13's, which was a respectable place to be back then. now we ask for far more.
I'm swapping one into my f150 (currently 5.0), 4wd, lifted, big tires, and maroon paint. It was great seeing this where I can see what it can do n/a and when I boost it like my Camaro
These videos are gold. I think that a lot of people can save a lot of money on their engine builds as well as having realistic expectations of their builds by watching the corresponding videos to the engine they want to build. Well done
First off - that was awesome. 10lb boost was impressive. Great example of a junkyard budget kick-ass build. The disappoint is like you said - what the results with the boost/carb would have been. Thanks Rich - appreciate your channel 😎
Angelo Vasilikos 👍 I came out of my Chevy shell years ago. I still love them, but loving on other brands really broadens your horizons and allows you more opportunity to enjoy other cool cars. I can make any of the GM, Ford, and mopars run good.
I got a 88 351W from my friends father. It came out of a tug (airport vehicle) where we worked. It was tired, had a tough life. I'd built a few mild 302's in my day. But my uncle talked me into the extra cubic inches. The swap to get it into my foxbody wasn't even difficult. Motor mounts, headers, etc. Went 30 over, 195 CC Trick flow heads, fresh rebuild. Stock rotating assembly with forged pistons. Lunati hydraulic flat tappet cam, forget what grind and lift. But it was very very streetable. Made power about 1500-6500. I'll never build another 302. 351W Is very much underrated. And the 94 Plus 351w was the hydraulic roller setup, too like he mentioned.
Also added a 100 wet shot plate kit. It was just a street car. Never could get traction. But it was awesome at roll racing. If i was a little older at that time, and made more money i would have finished it.
At first I wasn't a fan of richard not using film from the actual dyno runs. But the more I watch. The more I appreciate this format. Full of good content. All business. No fat.
What amazes me about this engine test is that you installed substantially larger heads and cam and torque between 2500 and 3000 didn't decrease but went UP 30 lb/ft!! This looks to be one of those rare "have your cake and eat it too" engine building successes!
@@richardholdener1727 I'll be going victor jr top end on my 73 351w. Probably do stock bottom end for now. Or I'm I better getting the newer 351w. Mines a stock rebuild with about 15k miles in my 69 mustang. Or should I just go stroker off top with my current 351
Back in the Day, 1980's I liked to build 351 Windsor Street Boss with 2V Cleveland heads and boy did it make sick power with the canted valves and free flowing exhaust ports :)
The windsor 351 is so underrated. Late ones like 93+ have roller capability too. I think I did a complete 351w swap in a fox for $2500. Kept mass air EFI a9l setup, fatter injectors, heads, cam and pro products typhoon intake. Made 415 WHP through a WC t5.
i see videos where folks swap the OHC in their Fox for a 302, and wonder why...might as well step it up and buy a 5.0 Mustang if that's what you want, it will be worth more later than a swap 302.
When I bought my first house 15 years ago I needed a truck to remodel my home. Trucks were kinda expensive so I found a 1995 extended econoline van with 5.8L 351W motor. Paid $1800 for it. Thought to myself that as soon as I’m done with remodeling I’ll sell it. Well, I still use it to this day. All these years it served me well and we used it for many trips along California coast and many trips to Lake Tahoe and Nevada. When I got the van it was under 200K and now it’s at 247K. Still runs strong. Even though it has some electrical gremlins, it’s not bad for $1800. Maybe one of these days I’ll do a complete overhaul of the engine. Cheers 🍻
Just what I was waiting for. Love all the blue oval content you can give us. Faithful watcher of all the daily videos. I second or third the big bang 351w.
I’d love to see a 351w based motor like this with a solid set of intake swaps. Specifically hi-ram vs rpm air gap vs victor jr in carb form and efi deluge as well... Hi-ram vs edelbrock vs tfs with both box top and long runner top.
Got damn, I'm 18 with my windsor set up damn near the same with edelbrock heads, the edelbrock dual plane air gap, and 750 holley. You're making the full vortech kit in my old man's garage sound extremely tempting.
I bought a Bronco last year and getting ready to buy a JY 351w to rebuild and spice up....was only expecting to get up to 300 hp with some spicing but this edelbrock package has me intrigued. Thanks for your hard work
The 351w is like a 302/5.0 on steroids. Bigger head bolts, rod bolts and main bolts. Beefier mains to hold that crank at 8000rpm. I built mine 24 yrs ago pushing 400 plus hp. I drive my hot rod mustang every other day and at least once every other weekend pull the quarter mile RPM's to 8000. The Crank is stock and balanced. Awesome video featuring a awesome motor that a lot of people overlook. Keep up the great work.
This video and your ones on making 2-3-4-500hp with a sbf inspired me to get a 351w for my 83 fox body. Supposedly a "good running engine". Bought off marketplace and buddy dropped it off. Very rusty engine..ok..came out of a fish plant truck..ok.. Next morning went out to a puddle of tar under it, the pan was rusted through. Drained the pan and it was tar, not oil, tar! Pull valvecovers and the sludge is to the top of the valve Springs! The oil filter was rusty, last oil change? Who knows. Broke 4exh bolts pulling manifolds. Broke a bell housing bolt pulling tranny off! Broke all four corner bolts pulling intake! Pulled a couple mains and rods...bearings are worn but crank is good, yay!! Can't pull water pump or timing cover off as bolts are twisting.(I can feel them) So, this was going to be a "stock 351 with 4bbl and long tubes" as an "in between" motor going from blown up 302 to 460. This would get me back on the track bracket racing next year. Yeah, well...this ain't turning out like a California wrecking yard engine.... You still inspired me though so can't see not doing it, but damn, talk about hard road for 250hp! Even if I stick on the gt40p heads I got, still only give me 270 or 280hp. Keep the Ford videos coming Richard, how about a stock 460 then just headers and 750? Small cam then intake, piece at a time?
What amazes me is how similar the Junkyard 351W's power and torque lays over your test with the Non PI 2v. Both made right at about 260fwhp at close to the same peak rpm, and even torque was similar only being about 15-20ft/lbs more in favor of the 351w.
I loved this video, I just picked up a 95 5.8 ford out of an f-250 a couple of months ago for just $50. I would love to see a test session aimed at peak torque for the 351w
Qwalay hey man you can find those mid 90’s ford trucks for cheap in rust belt areas because of rusting frames...for 300-700 bucks, you can sell the running gear and make more money on it than you paid for while being able to keep the engine for yourself...same thing goes for gm trucks and cargo vans with vortec 350’s and the 4.8,5.3.6.0 LS motors...300-1000 bucks...if you get lucky and find an s10 with the rare 8.5 rear end with the lsd option you can literally sell that for anywhere around 900-1500 bucks depending on how nice and shiny you can make it
That is a good price, I live in the rust belt and paid $100 for a roller block and EFI intake with wiring--I'd be tossing the rest anyway. But I have a pair of $50 Chevy 4 bolt blocks I picked up just before the pandemic..and yesterday from an estate sale :) The deals are out there, but you have to hunt, and I'm limited to what I can toss into the trunk of a Ford Escort since I no longer have a pickup :( so many olds 455/pontiac 400's I've had to let pass by for only a few hundred b/c they weren't dissassembled.
True :) I live in a humid area, so my dry space has run out. Mustangs Unlimited went out of business where I live, I just grabbed about 8 soda boxes full of free magazines they had lying around. I keep telling myself, take the money I'm using to grab cheap parts and save it up to spend on the cars lying around, but you know how it goes...its hard to pass up deals :) My problem is I begin losing track of what I do have, when I see a deal on something, and I end up with two. Its long past time to get organized. The stuff is out there to get, its just all over the place and needs to be hunted down. Half the fun of the deal is finding it. Tho with this pandemic, the swap meets and flea markets are taking a break. I once picked up a chrome dress up kit (valve covers, timing cover, alternator) for a Chevy small block for $10 at a tag sale. But the other 10 tag sales I stopped to check out were busts. Still, how long does it take to walk a tag sale? Another time I got a Victor Jr intake for same price, arrived at my destination 5 minutes late as a result. Its worth it to me. It may not be to others.
Heck yeah Richard 43k subs, it’s going up fast!!! I subbed a little while ago and binged every vid. I love every vid and truly appreciate your work and keep it going buddy!
Great video for me as I'm tossing up whether to go Cleveland or Windsor 351 for an upcoming engine conversion. From what I've read - and watched on youtube - the Windsor seems to offer more bang for the buck. And it's more compact dimensions are another big plus. If you've made a video comparing the two I'd love to see it. Just subscribed...thanks Richard.
Loving the videos mate keep them up, I'm building a 408 stroker Cleveland engine here in chch nz for my falcon that's also getting a turbo so you've been ever so helpful.
I had a stock 351w in my bronco. Went to 408 with isky cam , stock heads touched up, wien stealth intake and edelbrock 600 carb. Wawawewa what a difference
Richard Holdner " alright guys let's stick to the formula. Junk yard motor check. Stock trim dyno check. NA upgrades and dyno check. Add boost and dyno check. Remember all cams are boost cams and always add boost. That's a rap." love it keep doing it man
My first and second cars both got the same 351w. I did a lot of reading back in the day to pick stuff that would work. It turns out that I was reading a lot of stuff written by frieberger and dulcich. The second car was an 81 tbird (early fox body.) That car was great, despite the wear and cancer. Most of the performance stuff eventually was dropped onto a junkyard 302 that still had the factory cross hatch.
Ive often wondered why the crankcase pressure is never checked, especially on boosted engines. That would certainly give an indication of ring seal. 🔔👍
Yes! Great timing Richard, just picked up a 351 in the JY here for a back-up build for when the 302 goes ⏱💣 Those HP & TQ numbers in a fox would be no joke in the street or track, Thanks for the knowledge! 👊
yessir, thank you for your time sir this is what i’m doin 351w .40 over JE flat tops with eyelashes eagle i beam rods Edelbrock top in kit and ten LBS of boost via super charger EFI tho easier to tune that way all neatly stashed away in a 95 step side 4x4 ford truck she’s not for the mud strictly the street the four wheel drive is just for fun
This is relevant to my interests!! Just put an E150 5.8 (flat tappet sadly) in my 57 Fairlane. Fitted with a vintage Offy intake and a 600cfm Holley. Been looking into what to do next - now I have my answer! Good to hear the dished pistons clear valves on the heads. Thanks for the video!!
Time to take that next step. Budget rebuild with stock rods, crank, etc and flat tops let's just see what you can do. What are the reasonable limits of a low buck build? Put the gap in and a blower cam to start, then twist away. Good article!!
It's been about 15 years since I've had a 351W but one thing I do remember is nothing woke it up like a dual plane cam. Even with heavy reworked heads getting the exhaust out of it was always the key.
Good point, it gets the intake design out of the way and compares apples to apples. Its no longer a wet to dry intake comparison, tho it is interesting the Edelbrock choice is supposed to be the middle ground between the classic long runner Windsor intake and the "bread box" aftermarket designs that kill the bottom end.
@@markprice2225 I’m building a 84.5 gt350 foxbody right now 351w aluminum heads/tr3650 5speed zex wet kit etc it’ll be fun. I went all out on weight savings too all tubular front end parts, aluminum drive shaft/fly wheel and more. It should be pretty fun
5.8 blocks can hold a couple hundred more ftlbs without splitting the block, that to me is worth it even if it didn’t make more power. Edit: Well shit Richard basically said the same thing lol
Richard could you do the same test with the EFI era 460 big blocks? Reason being is I was always told they are boat anchors. I'm running one with an upgraded fuel system and tuning with a moates quarterhorse. Just adding mass air, 80 lb injectors, lightning MAF, and more timing made a huge difference. Then I found a vortech v1 supercharger kit. It's making 8.8 psi at 6000 RPM. I have no clue how much HP it's making but I can say it's more fun than my stock LS3 Corvette. I don't comment often, but I want to say I appreciate the tests that you do.
This 351 did really good with the Edelbrock top end kit. I hear that a 350 sbc will make phenomenal power and torque with an Edelbrock E-170 top end kit.
Did the same set up a few many years ago . Right out of a jusk yard . We used the f cam , twisted wedge head and ported truck lower intake , bread box upper with a 75 TB and 80 C&L . We were at 453 hp End up with a 250 shot for a little extra fun . Still running today . Never opened it up but it'sgetting tired .lol.
@@MegaMustangkiller same, there's a great amount of content her for sbf and sbc guys. No love yet for the sbm though which is a pity coz it's a brilliant motor. And wrecking yards are full of magnums.
There is a few large construction companies here where I live and they always used F250 and 350s. Even when they were able to get a 460, it was 351 in the trucks. But all of the E250-350s had 300 sixes. They typically had about fifty trucks and 25 vans. They would wear out bodies and frames before they killed the engine.
The 351W was really made for the full-size cars, as to be the stop gap between the 302 and the 390 (1969 here) and so it was designed to haul 5-6000lb cars loaded down with camping gear and pulling an airstream. (same as F150/250 trucks) Even after the 351C which was superior in Horsepower came out, the 351W was the Standard for Full Sized Ford Station Wagons, as it was more durable and had much more off-idle torque than the 351C. - The fact that emissions were killing compression and there was no longer a need for "High RPM Performance engines" so thats why the Cleveland was phased out in 74. - The 400 which came out in 71 and replaced the 390 in 72 (Full-size cars) was then destroked with basically a 351W Crank, and made the 351M (we all know what kind if turd that was, had crappy oiling system too, as did the 351C and 400) Thank god that crap only lasted to 82! - The 351W though not superior in Horsepower, was definitely superior to 351C/M in durability. 1969-1997 is a long time for one sub 6L engine, only the 302 and 300-6 surpass it. (Yes, I know the 429/460 were also up there too, but we are talking SBF and sub 6L engines.)
You should do a supercharger and turbo battle for the 351 💪🏾 I'm going to install a 351 in my fox and that would be interesting to know which one to go with on a efi set up
Yep big fan of the 351w and swapped one into my mustang II out of a 69 mustang way before hotrod made it popular.......still have it but newer windsor now. I didnt have all the go fast parts like today, so had to accomplish that with good factory parts and cubic inches. Keep up the good work. 👍😁👍
I'm a fan of your work and really appreciate the effort you take to put out this content, WOW!!! That said, I'd love to see a low buck type of build on a fox 302. Stock pistons turned around, optimize quench with gasket thickness, windage tray, etc. Would really love to see what you could do with some gt40's on a setup like that. E7 to gt40 to ported gt40 :-) I know everyone says don't waste your time on those, but fact is a lot of people dont have the budget so they start out with some junkyard heads. Then later want a little more....ie porting ;-) Thank you.
Richard do you recall what injectors were used for the EFI setups, N/A and Boosted? These videos are so full of data we all appreciate your work very much!
Richard as usual, boost makes more power! But what is the draw back behind force induction? Why didn't GM embrace it with Buick and Pontiac? With GM tinkering with turbos since the late 70's and the success with the 3.8 liter in the 80's. GM should have been at the forefront of force induction, by the beginning of the millennium.
i had this basic combination 20 years ago i had the rpm intake than latter the air gap onthis combo was good for a tenth or two i had the flat tappet rpm cam 224 234 duration . 500 / 520 lift and to top it off i had the original twisted wedge heads it only had 8,5 compression because 72 deep dish pistons but did it make torque and hp . it was in a 1981 mercury cougar with a c4 2500 stall and 3.73 gears. the car ran 12.60s at 110 mph it was 3700 with driver . had i removed the cv joint at the back of the drive shaft it may have shaved off a couple of tenths . the joint weight was 15 lbs the windsor is one of the best engines any company ever made . the 5 0 guys need to learn 5 8 is the only way to go unless its a boss 9
Yes the Windsor and Cleveland are basically same blocks one is 4 bolt mains and bigger valves better flow heads . Bigger cam and roller or solid lifters ect. The slug Windsor's only take a few add one for serious power gains. Great motor for any old ford . My friend had a Windsor slug engine in 1966 fairlane. Once he did the cam and heads and few minor changes that pig flew good and was over 500 rear wheel hp 575 HP Sweet
Thank you!!! You have helped me make a decision on the intake manifold dilema. Now I’m not taking anything away from the eldebrock intake manifold but I always wonder if the GT40 intake manifold were better but thank you anyways in doing a 351W
I'm literally in the process of buying a 96 250 with this motor. well now I know what I'm going to do when I finally have any kind of issue in the motor
I prefer EFI for the tunability, but the manifold was the reason for the power loss, I can almost guarantee it. It went from a relatively short intake and straight flowing induction system (carb) to one that's much longer and not as direct (EFI). If the EFI had a manifold runner length similar to the carb manifold, I'd be it would make the same if not a hair more power
HotMetal524 Yeah, I think that if they kept the manifold and just swapped the carb for a Sniper or something similar that would work with the same manifold, it would have made the same or more power.
Awesome stuff , I’ve got a 351 C with 750 Holley in my ‘79 F-100 Ranger XLT ...yes I will definitely go with edelbrock , I was going to E.F.i it but wow this video changed my mind , thank you , I would like to see a video with a 351 Cleveland, this engine is legendary in Australia 🇦🇺 the tooling got send to Australia back in late 60’s we love it .
Every Ford has horrible exh ports. When I ran clevelands back in the day I couldn't figure out why thos big sewer ports wouldn't flow. Raised the floor and increased velocity and bam! But windsors, clevelands, fe's even 385 series's exh ports suck with that tight turn. Wish Ford would of made the exh come out the side of the engine instead of pointing down. The only reason it was a 200hp jump is because it started from such a low number. Most fords are .52-.58 hp per cube from the factory, lots of room for improvement.
@@jimmiller4667 Great comment......this is exactly what I experienced on the Ford engines. I've built several 429-460's with the stock heads and saw the same results. As soon as I ported the exhausts to lead the gas flow to the top of the port and filled the "dead" part of the port with Devcon F, the flow rate picked up and the engine made more power. The reason for the 'U-turn' exhaust ports was the shock towers on the Mustangs jutting in and squeezing the port into that miserable configuration. Throw on a good aluminum head with 'D' ports and, ZAP!, the power appears. I like all engines but would like to see more Ford stuff because we are inundated with Chevy small block and LS motors all the time and there's a lot of info already out there on those mills.
When Ford invented the Windsor low deck (221-260-289-302) it was destined for the Falcon chassis, which had the famous shock towers in the way. That is why the exhaust port was so bad, and even the mighty Cleveland had issues--racers would just cut the exhaust port right off the side of the head and weld on a pipe to be the port coming out at a better angle, back in the 1970's (look up the old magazines if you don't believe it). What also hurt the flow was, compared to a same displacement Chevy, was smaller valves and port size. It helped low RPM torque production, but if you wanted flow, Ford expected you to buy a Tunnel Port 289 head over the counter(predecessor to the Boss 302 in 1967), a Boss 302, or a Cleveland. Or just go to a 427 big block. And check out the carb sizes--the 289 K code Challenger had what, a 585 cfm carb or something? As soon as Shelby gave it a bigger carb, intake, and Tri Y headers, it went over 1hp/inch.

Cheaper option would be to get a cam similarly to the package one, slap an appropriate carb on it, with intake.

Easy to forget how much potential the 351W has.
And this combo is with stock cast pistons.
Man, I am blown away that the top end package added 200 HP!! What I would have given to have had that back in the day.
It has 5,969" connecting rods, 3/8" rod bolts and 1/2" head bolts! Bolts right up where the 302 does! The block is strong enough to shoot 150 pass after pass. We shot 150 on Speed Pro cast pistons, just backed the timing back 6 degrees! Cheap, dependable fun!
E7s were that bad and the stock cams were that poor. Not saying they can't be made to work but man it's easy now for something like that.
@@thetriode those were designed for low RPM torque--a good tuner can get a stock 5.0 into the mid 13's, which was a respectable place to be back then. now we ask for far more.

These videos are dangerous. Now I want to build a ford as well and I’m a Chevy guy lol. Great videos!
Angelo Vasilikos 👍 I came out of my Chevy shell years ago. I still love them, but loving on other brands really broadens your horizons and allows you more opportunity to enjoy other cool cars. I can make any of the GM, Ford, and mopars run good.
@@mistered9435 In other words, ya can make that horse talk...
kram Null
LOL...wink wink
Angelo Vasilikos Same here lol.
Same. I've got a ZL1 camaro in the driveway but I just found myself looking for a Fox hatchback 5-spd to drop a boosted 351w into, lol.
Keep the Ford content coming sir! I'd like to see how the Victor 5.8 manifold stacks up.
I got a 88 351W from my friends father. It came out of a tug (airport vehicle) where we worked. It was tired, had a tough life. I'd built a few mild 302's in my day. But my uncle talked me into the extra cubic inches. The swap to get it into my foxbody wasn't even difficult. Motor mounts, headers, etc. Went 30 over, 195 CC Trick flow heads, fresh rebuild. Stock rotating assembly with forged pistons. Lunati hydraulic flat tappet cam, forget what grind and lift. But it was very very streetable. Made power about 1500-6500. I'll never build another 302. 351W Is very much underrated. And the 94 Plus 351w was the hydraulic roller setup, too like he mentioned.
Also added a 100 wet shot plate kit. It was just a street car. Never could get traction. But it was awesome at roll racing. If i was a little older at that time, and made more money i would have finished it.
At first I wasn't a fan of richard not using film from the actual dyno runs. But the more I watch. The more I appreciate this format. Full of good content. All business. No fat.
What amazes me about this engine test is that you installed substantially larger heads and cam and torque between 2500 and 3000 didn't decrease but went UP 30 lb/ft!! This looks to be one of those rare "have your cake and eat it too" engine building successes!
not unusual when compared to stock heads
@@richardholdener1727 I'll be going victor jr top end on my 73 351w. Probably do stock bottom end for now. Or I'm I better getting the newer 351w. Mines a stock rebuild with about 15k miles in my 69 mustang. Or should I just go stroker off top with my current 351
Back in the Day, 1980's I liked to build 351 Windsor Street Boss with 2V Cleveland heads and boy did it make sick power with the canted valves and free flowing exhaust ports :)
Glad you are showing us Ford guys some love. Love the videos. Keep up the hard work.
The windsor 351 is so underrated. Late ones like 93+ have roller capability too. I think I did a complete 351w swap in a fox for $2500. Kept mass air EFI a9l setup, fatter injectors, heads, cam and pro products typhoon intake. Made 415 WHP through a WC t5.
i see videos where folks swap the OHC in their Fox for a 302, and wonder why...might as well step it up and buy a 5.0 Mustang if that's what you want, it will be worth more later than a swap 302.
@@alertgasperunless you have a Z7 zephyr that's an OG 302 like mine. Even harder to get than a fox
When I bought my first house 15 years ago I needed a truck to remodel my home. Trucks were kinda expensive so I found a 1995 extended econoline van with 5.8L 351W motor. Paid $1800 for it. Thought to myself that as soon as I’m done with remodeling I’ll sell it. Well, I still use it to this day. All these years it served me well and we used it for many trips along California coast and many trips to Lake Tahoe and Nevada. When I got the van it was under 200K and now it’s at 247K. Still runs strong. Even though it has some electrical gremlins, it’s not bad for $1800. Maybe one of these days I’ll do a complete overhaul of the engine. Cheers 🍻
That heads cam and intake really took that engine from zero to hero
Primarily the cam. Those truck cams are complete dogs, but since they were intended for pulling it makes sense.
@@Dirtilike1 yeah but aren't you severely limited on valve opening before bottoming out with unmodified factory heads.
@@compted10 You can run an e303 cam without issue. That is probably plenty.
Yes, always a Ford guy myself and love seeing different engine combos making power! N/A is what I’ve always done but tempted to go turbo someday
Thanks!
Just what I was waiting for. Love all the blue oval content you can give us. Faithful watcher of all the daily videos. I second or third the big bang 351w.
These are definitely better than the 5.0, and fit most early mustangs without issue. Kickass video, thanks.
I’d love to see a 351w based motor like this with a solid set of intake swaps. Specifically hi-ram vs rpm air gap vs victor jr in carb form and efi deluge as well... Hi-ram vs edelbrock vs tfs with both box top and long runner top.
Got damn, I'm 18 with my windsor set up damn near the same with edelbrock heads, the edelbrock dual plane air gap, and 750 holley. You're making the full vortech kit in my old man's garage sound extremely tempting.
My 2 dream videos are a rotatory and/or 4.9 Ford big six being boosted to the moon!
I bought a Bronco last year and getting ready to buy a JY 351w to rebuild and spice up....was only expecting to get up to 300 hp with some spicing but this edelbrock package has me intrigued. Thanks for your hard work
The 351w is like a 302/5.0 on steroids. Bigger head bolts, rod bolts and main bolts. Beefier mains to hold that crank at 8000rpm. I built mine 24 yrs ago pushing 400 plus hp. I drive my hot rod mustang every other day and at least once every other weekend pull the quarter mile RPM's to 8000. The Crank is stock and balanced.
Awesome video featuring a awesome motor that a lot of people overlook. Keep up the great work.
That’s amazing how much just cylinder heads and a cam can do to these ol motors
This video and your ones on making 2-3-4-500hp with a sbf inspired me to get a 351w for my 83 fox body. Supposedly a "good running engine". Bought off marketplace and buddy dropped it off. Very rusty engine..ok..came out of a fish plant truck..ok..
Next morning went out to a puddle of tar under it, the pan was rusted through. Drained the pan and it was tar, not oil, tar! Pull valvecovers and the sludge is to the top of the valve Springs! The oil filter was rusty, last oil change? Who knows. Broke 4exh bolts pulling manifolds. Broke a bell housing bolt pulling tranny off! Broke all four corner bolts pulling intake!
Pulled a couple mains and rods...bearings are worn but crank is good, yay!! Can't pull water pump or timing cover off as bolts are twisting.(I can feel them)
So, this was going to be a "stock 351 with 4bbl and long tubes" as an "in between" motor going from blown up 302 to 460. This would get me back on the track bracket racing next year. Yeah, well...this ain't turning out like a California wrecking yard engine.... You still inspired me though so can't see not doing it, but damn, talk about hard road for 250hp! Even if I stick on the gt40p heads I got, still only give me 270 or 280hp.
Keep the Ford videos coming Richard, how about a stock 460 then just headers and 750? Small cam then intake, piece at a time?
What amazes me is how similar the Junkyard 351W's power and torque lays over your test with the Non PI 2v. Both made right at about 260fwhp at close to the same peak rpm, and even torque was similar only being about 15-20ft/lbs more in favor of the 351w.
I loved this video, I just picked up a 95 5.8 ford out of an f-250 a couple of months ago for just $50. I would love to see a test session aimed at peak torque for the 351w
Damn wish i could get a 351 for $50
Qwalay hey man you can find those mid 90’s ford trucks for cheap in rust belt areas because of rusting frames...for 300-700 bucks, you can sell the running gear and make more money on it than you paid for while being able to keep the engine for yourself...same thing goes for gm trucks and cargo vans with vortec 350’s and the 4.8,5.3.6.0 LS motors...300-1000 bucks...if you get lucky and find an s10 with the rare 8.5 rear end with the lsd option you can literally sell that for anywhere around 900-1500 bucks depending on how nice and shiny you can make it
That is a good price, I live in the rust belt and paid $100 for a roller block and EFI intake with wiring--I'd be tossing the rest anyway. But I have a pair of $50 Chevy 4 bolt blocks I picked up just before the pandemic..and yesterday from an estate sale :) The deals are out there, but you have to hunt, and I'm limited to what I can toss into the trunk of a Ford Escort since I no longer have a pickup :( so many olds 455/pontiac 400's I've had to let pass by for only a few hundred b/c they weren't dissassembled.
@@albertgaspar627 man, if I had room for a bunch of 455's, I'd have room to store a trailer. Even an Escort can pull a drag week style trailer...
True :) I live in a humid area, so my dry space has run out. Mustangs Unlimited went out of business where I live, I just grabbed about 8 soda boxes full of free magazines they had lying around. I keep telling myself, take the money I'm using to grab cheap parts and save it up to spend on the cars lying around, but you know how it goes...its hard to pass up deals :) My problem is I begin losing track of what I do have, when I see a deal on something, and I end up with two. Its long past time to get organized.
The stuff is out there to get, its just all over the place and needs to be hunted down. Half the fun of the deal is finding it. Tho with this pandemic, the swap meets and flea markets are taking a break. I once picked up a chrome dress up kit (valve covers, timing cover, alternator) for a Chevy small block for $10 at a tag sale. But the other 10 tag sales I stopped to check out were busts. Still, how long does it take to walk a tag sale? Another time I got a Victor Jr intake for same price, arrived at my destination 5 minutes late as a result.
Its worth it to me. It may not be to others.
Heck yeah Richard 43k subs, it’s going up fast!!! I subbed a little while ago and binged every vid. I love every vid and truly appreciate your work and keep it going buddy!
thnx-I love to dyno
Content like this, it should be 43,000,000.
Great video for me as I'm tossing up whether to go Cleveland or Windsor 351 for an upcoming engine conversion. From what I've read - and watched on youtube - the Windsor seems to offer more bang for the buck. And it's more compact dimensions are another big plus. If you've made a video comparing the two I'd love to see it.
Just subscribed...thanks Richard.
Man right to the point. And no B.S. Really wish more people would go your route. So nice when short on time. Thanks
Loving the videos mate keep them up, I'm building a 408 stroker Cleveland engine here in chch nz for my falcon that's also getting a turbo so you've been ever so helpful.
I had a stock 351w in my bronco. Went to 408 with isky cam , stock heads touched up, wien stealth intake and edelbrock 600 carb. Wawawewa what a difference
Richard Holdner " alright guys let's stick to the formula. Junk yard motor check. Stock trim dyno check. NA upgrades and dyno check. Add boost and dyno check. Remember all cams are boost cams and always add boost. That's a rap."
love it keep doing it man
My first and second cars both got the same 351w. I did a lot of reading back in the day to pick stuff that would work. It turns out that I was reading a lot of stuff written by frieberger and dulcich.
The second car was an 81 tbird (early fox body.) That car was great, despite the wear and cancer.
Most of the performance stuff eventually was dropped onto a junkyard 302 that still had the factory cross hatch.
Ive often wondered why the crankcase pressure is never checked, especially on boosted engines. That would certainly give an indication of ring seal. 🔔👍
Wow, I just commented on the last video about this exact video. And here is the video after I refreshed my page! Love it! lol
Yes! Great timing Richard, just picked up a 351 in the JY here for a back-up build for when the 302 goes ⏱💣 Those HP & TQ numbers in a fox would be no joke in the street or track, Thanks for the knowledge! 👊
One day I hope to add boost to the 351w in my Falcon. Great video as always🍻
Awesome video! I'm thinking about a 351 swap at some point. I learned about the Edelbrock package here, that is worth the price of admission!
Haha this man inspired me with his twin turbo 5.8 build years ago and now he does a nice dyno vid on it again. Love it
Sweet! Overhauled a 351w. And used as inboard. It performed awesomely. Back in the 80s. 👍
yessir, thank you for your time sir this is what i’m doin 351w .40 over JE flat tops with eyelashes eagle i beam rods Edelbrock top in kit and ten LBS of boost via super charger EFI tho easier to tune that way all neatly stashed away in a 95 step side 4x4 ford truck she’s not for the mud strictly the street the four wheel drive is just for fun
This is relevant to my interests!! Just put an E150 5.8 (flat tappet sadly) in my 57 Fairlane. Fitted with a vintage Offy intake and a 600cfm Holley. Been looking into what to do next - now I have my answer! Good to hear the dished pistons clear valves on the heads.
Thanks for the video!!
I got a 87 bronco 351w I believe and dropped into my 67 ltd
I like EFI for certain applications, especially boost. With that being said I'll always love carburetors for N/A builds and nitrous applications.
Love these videos, especially since im trying decide whether to build a ford motor or an LS. No shortness of information.
Factory testing = J1349. I appreciate your clarifications. And, BTW, excellent video!
Time to take that next step. Budget rebuild with stock rods, crank, etc and flat tops let's just see what you can do. What are the reasonable limits of a low buck build? Put the gap in and a blower cam to start, then twist away. Good article!!
It's been about 15 years since I've had a 351W but one thing I do remember is nothing woke it up like a dual plane cam. Even with heavy reworked heads getting the exhaust out of it was always the key.
Should do a test between carb and TBI(holley sniper) to see hp and tq difference.
Was thinking the same damn thing man
Andrew Wihlon I agree, I have a Holley Sniper on my 351w
Good point, it gets the intake design out of the way and compares apples to apples. Its no longer a wet to dry intake comparison, tho it is interesting the Edelbrock choice is supposed to be the middle ground between the classic long runner Windsor intake and the "bread box" aftermarket designs that kill the bottom end.
Another great episode. So much information in just a short time.Thanks Richard
Glad I found your page! You're super informative and your videos are definitely more interesting than powernation and enginemasters
Dude you are amazing!! thank you for the video on the 351w
I've never seen a split 5.0 block, maybe you should split one for a video. Boost til she lets go.
Tony Baldwin BREW2L has a split 302 that he’s taking apart now, i hadn’t seen one either till then 😳 200 shot did that one in.
I broke crankshaft but never split a block.Now was the block flexing or did the cranks just give up I'm not sure
Then you have never seen one make much power.
I split one a 600 wheel. The only part not split was that think piece of metal at the rear of the lower intake.
I split one with 500ish hp and constant 7500 rpm shifts. Broke down the lifter valley to the mains.
Please do more 351w stuff I’ve watched this video like 10times through since it was posted🤣 there’s not enough small block Ford videos on the internet
Love it too! I have seen foxbody mustangs with bored out 351 Windsor and a Procharger make 1000rwhp & that was with boost set about midway
@@markprice2225 I’m building a 84.5 gt350 foxbody right now 351w aluminum heads/tr3650 5speed zex wet kit etc it’ll be fun. I went all out on weight savings too all tubular front end parts, aluminum drive shaft/fly wheel and more. It should be pretty fun
5.8 blocks can hold a couple hundred more ftlbs without splitting the block, that to me is worth it even if it didn’t make more power.
Edit: Well shit Richard basically said the same thing lol
Richard could you do the same test with the EFI era 460 big blocks? Reason being is I was always told they are boat anchors. I'm running one with an upgraded fuel system and tuning with a moates quarterhorse. Just adding mass air, 80 lb injectors, lightning MAF, and more timing made a huge difference. Then I found a vortech v1 supercharger kit. It's making 8.8 psi at 6000 RPM. I have no clue how much HP it's making but I can say it's more fun than my stock LS3 Corvette.
I don't comment often, but I want to say I appreciate the tests that you do.
This 351 did really good with the Edelbrock top end kit. I hear that a 350 sbc will make phenomenal power and torque with an Edelbrock E-170 top end kit.
Did the same set up a few many years ago . Right out of a jusk yard . We used the f cam , twisted wedge head and ported truck lower intake , bread box upper with a 75 TB and 80 C&L . We were at 453 hp
End up with a 250 shot for a little extra fun .
Still running today . Never opened it up but it'sgetting tired .lol.
Loving the variety. I'm gonna keep requesting some mopar content though. Preferably pre g3 hemi! 😆
Brian Frost Like 400/440 BB with cheap Chinese heads (440 source or pro comp?) and a VS turbo!!!!! Of course Cam, springs, and gap.
Richard did some interesting tests on a 5.7 hemi a while ago. Check it out.
Wouldn’t mind seeing some 318/360 magnum stuff
@@edberry78 yes he did, really keen to see some pre gen 3 hemi stuff though coz it's only a fraction the price of hemi stuff.
@@MegaMustangkiller same, there's a great amount of content her for sbf and sbc guys. No love yet for the sbm though which is a pity coz it's a brilliant motor. And wrecking yards are full of magnums.
There is a few large construction companies here where I live and they always used F250 and 350s. Even when they were able to get a 460, it was 351 in the trucks. But all of the E250-350s had 300 sixes. They typically had about fifty trucks and 25 vans. They would wear out bodies and frames before they killed the engine.
The 351W was really made for the full-size cars, as to be the stop gap between the 302 and the 390 (1969 here) and so it was designed to haul 5-6000lb cars loaded down with camping gear and pulling an airstream. (same as F150/250 trucks) Even after the 351C which was superior in Horsepower came out, the 351W was the Standard for Full Sized Ford Station Wagons, as it was more durable and had much more off-idle torque than the 351C. - The fact that emissions were killing compression and there was no longer a need for "High RPM Performance engines" so thats why the Cleveland was phased out in 74. - The 400 which came out in 71 and replaced the 390 in 72 (Full-size cars) was then destroked with basically a 351W Crank, and made the 351M (we all know what kind if turd that was, had crappy oiling system too, as did the 351C and 400) Thank god that crap only lasted to 82! - The 351W though not superior in Horsepower, was definitely superior to 351C/M in durability. 1969-1997 is a long time for one sub 6L engine, only the 302 and 300-6 surpass it. (Yes, I know the 429/460 were also up there too, but we are talking SBF and sub 6L engines.)
You should do a supercharger and turbo battle for the 351 💪🏾 I'm going to install a 351 in my fox and that would be interesting to know which one to go with on a efi set up
I have a 351w with a solid roller cam... 615 lift. Aluminum heads with 1.60. 2.02 valves flat top pistons. And a 780 pro systems carb. It’s a beast!
I have two vehicles with a 351 Windsor in them. A 2003 E150 with 350000 miles on it and a 73 Mustang. I am a believer. Best engine ever.
A 2003 Econoline V8 will have a 4.6 or a 5.4...The last 351W was in a van was 1996.
I would like to see you do the same thing with the 5.2 or 5.9 dodge magnums. Lots of them around and still popular!
Yep big fan of the 351w and swapped one into my mustang II out of a 69 mustang way before hotrod made it popular.......still have it but newer windsor now. I didnt have all the go fast parts like today, so had to accomplish that with good factory parts and cubic inches. Keep up the good work. 👍😁👍
Thank you for explaining your dyno process.
Richard, while your in there, how about see what combinations make the best torque, say for a truck pulling a boat, campers, ect.
So cool to see these fords getting some love
I'm a fan of your work and really appreciate the effort you take to put out this content, WOW!!! That said, I'd love to see a low buck type of build on a fox 302. Stock pistons turned around, optimize quench with gasket thickness, windage tray, etc. Would really love to see what you could do with some gt40's on a setup like that. E7 to gt40 to ported gt40 :-) I know everyone says don't waste your time on those, but fact is a lot of people dont have the budget so they start out with some junkyard heads. Then later want a little more....ie porting ;-) Thank you.
Richard do you recall what injectors were used for the EFI setups, N/A and Boosted?
These videos are so full of data we all appreciate your work very much!
80 POUNDS
@@richardholdener1727 thank you 👍🏽
Richard as usual, boost makes more power! But what is the draw back behind force induction? Why didn't GM embrace it with Buick and Pontiac? With GM tinkering with turbos since the late 70's and the success with the 3.8 liter in the 80's. GM should have been at the forefront of force induction, by the beginning of the millennium.
I love the little Henry stuff
I love this he shows some good ideas for engines
i had this basic combination 20 years ago i had the rpm intake than latter the air gap onthis combo was good for a tenth or two i had the flat tappet rpm cam 224 234 duration . 500 / 520 lift and to top it off i had the original twisted wedge heads it only had 8,5 compression because 72 deep dish pistons but did it make torque and hp . it was in a 1981 mercury cougar with a c4 2500 stall and 3.73 gears. the car ran 12.60s at 110 mph it was 3700 with driver . had i removed the cv joint at the back of the drive shaft it may have shaved off a couple of tenths . the joint weight was 15 lbs the windsor is one of the best engines any company ever made . the 5 0 guys need to learn 5 8 is the only way to go unless its a boss 9
Yes the Windsor and Cleveland are basically same blocks one is 4 bolt mains and bigger valves better flow heads . Bigger cam and roller or solid lifters ect. The slug Windsor's only take a few add one for serious power gains. Great motor for any old ford . My friend had a Windsor slug engine in 1966 fairlane. Once he did the cam and heads and few minor changes that pig flew good and was over 500 rear wheel hp 575 HP Sweet
Richard, you are the best. Thank you.
Love this channel but I'd love to see you wrenching on the engine and also see the dyno pulls.
Years ago I replaced an LG4 with an LM1, no other changes. It was worth it just for the low-rpm torque improvement.
Thanks i love to see what can be done on a budget build with off the shelf parts
little...
Thank you!!! You have helped me make a decision on the intake manifold dilema. Now I’m not taking anything away from the eldebrock intake manifold but I always wonder if the GT40 intake manifold were better but thank you anyways in doing a 351W
I'm literally in the process of buying a 96 250 with this motor. well now I know what I'm going to do when I finally have any kind of issue in the motor
$15,000-$20,000 + for the last level with nothing done to the short block
That face when EFI makes less power everywhere....lol. Love ya richard!
I prefer EFI for the tunability, but the manifold was the reason for the power loss, I can almost guarantee it. It went from a relatively short intake and straight flowing induction system (carb) to one that's much longer and not as direct (EFI). If the EFI had a manifold runner length similar to the carb manifold, I'd be it would make the same if not a hair more power
Less airflow. Period.
Big Dogs makes them flow... And stealthy.
HotMetal524 Yeah, I think that if they kept the manifold and just swapped the carb for a Sniper or something similar that would work with the same manifold, it would have made the same or more power.
The 351W was a bolt in where the 302W was in my Galaxie 500. Alot more torkie motor even in stock form!
This man is definitely one of the best of the best!! I love his videos and they are always full of details and such!! I love it!!
Loved the 400 stuff. 351w>350 imo. Good stuff richard
+200HP Holy shit! I'm not longer looking for HCI for my stock 302... Im now looking for a 351W!
Awesome stuff , I’ve got a 351 C with 750 Holley in my ‘79 F-100 Ranger XLT ...yes I will definitely go with edelbrock , I was going to E.F.i it but wow this video changed my mind , thank you , I would like to see a video with a 351 Cleveland, this engine is legendary in Australia 🇦🇺 the tooling got send to Australia back in late 60’s we love it .
Love your channel! Always very interesting!
Love 351w stuff. Love it. Would love to see a single plane and elbow ls92 or 102 throttle and your twin s 475.
single plane loses a lot of low speed torque, but turbos work
Another great Ford SB video. Thank you.
Glad to see some sbf stuff keep it up!!
love the video just what I thought it would do but been wanting to know thanks
WOW - Dude, just a top end system did that much?! Shows you how conservative that old Ford stuff really was!
A truck 350 or 360 from the same era is in about the same boat.
They also had to meet emissions regulations, retain long term reliability, and be able to put a warranty on it. Even today stuff is left on the table.
Every Ford has horrible exh ports. When I ran clevelands back in the day I couldn't figure out why thos big sewer ports wouldn't flow. Raised the floor and increased velocity and bam! But windsors, clevelands, fe's even 385 series's exh ports suck with that tight turn. Wish Ford would of made the exh come out the side of the engine instead of pointing down. The only reason it was a 200hp jump is because it started from such a low number. Most fords are .52-.58 hp per cube from the factory, lots of room for improvement.
@@jimmiller4667 Great comment......this is exactly what I experienced on the Ford engines. I've built several 429-460's with the stock heads and saw the same results. As soon as I ported the exhausts to lead the gas flow to the top of the port and filled the "dead" part of the port with Devcon F, the flow rate picked up and the engine made more power. The reason for the 'U-turn' exhaust ports was the shock towers on the Mustangs jutting in and squeezing the port into that miserable configuration. Throw on a good aluminum head with 'D' ports and, ZAP!, the power appears. I like all engines but would like to see more Ford stuff because we are inundated with Chevy small block and LS motors all the time and there's a lot of info already out there on those mills.
When Ford invented the Windsor low deck (221-260-289-302) it was destined for the Falcon chassis, which had the famous shock towers in the way. That is why the exhaust port was so bad, and even the mighty Cleveland had issues--racers would just cut the exhaust port right off the side of the head and weld on a pipe to be the port coming out at a better angle, back in the 1970's (look up the old magazines if you don't believe it).
What also hurt the flow was, compared to a same displacement Chevy, was smaller valves and port size. It helped low RPM torque production, but if you wanted flow, Ford expected you to buy a Tunnel Port 289 head over the counter(predecessor to the Boss 302 in 1967), a Boss 302, or a Cleveland. Or just go to a 427 big block. And check out the carb sizes--the 289 K code Challenger had what, a 585 cfm carb or something? As soon as Shelby gave it a bigger carb, intake, and Tri Y headers, it went over 1hp/inch.
