Richard is an animal that sprinkles piston rings on his Wheaties and chews on rod caps for lunch. He will run the jankiest of setups for they are just future sustenance to be consumed.
"We weren't spinning it fast" Shows a vortech with 2 cracked impeller blades...that was funny. In the end, so a 347 has power adder potential of 700+HP. when done right. In such a simple and light package.
The other night we were at a cruise in and an elderly man was looking at our crown vic frame swap F-100 and he thought the 2 valve 4.6 was a Chevrolet motor. I told him what it was and he told me that engine would run longer than a small block because it has 5 main bearings and and small blocks only have 4. I was taught to respect my elders, so I held my tongue. So, Richard, you are really flirting with disaster with that 347 since it only has 4 main bearings!! Be careful!!! Here's a test for you, Big bang on a small block Chevy, Ford and Mopar with 1 bearing sitting on the bench!!! Thanks!
To much cam. I think with a smaller cam it would have made the same power but leveled off up top instead of wasting all the power that was left on the table. JMO. I love the picture of the fins damaged on the supercharger!!!!!
Sounds like my motor. CHP stroker kit, eagle5.4 rods, CHP LW140 pistons, offset ground 3.4 Cleveland, first gen ported twist wedge, custom Isky. 550 226/230 duration 114 lobe smog cam, vortec V 1 s trim meant to pass cali smog. Hoping for 600 hp.
YES! Sitting here drinking my coffee, seen the notice and went straight to it!! In your opinion..if you had them side by side and had to pick one for a daily driver, blown 331 or 347? If you get a chance, be cool to see muffler shootout using the 5.0 or 5.0.based engine. Or.some good "street" engine builds. I'm buiding a blown 331 for daily driver. Ill get a time slip, but only a couple.. but building it to travel and just have a nice.driver with ac
Drinking my coffee to and checking emails. I would like the 347 for the bigger and more balanced torque curve. I’m building a 5.7 to 6.4 .020 over 394 Hemi stroker, it’s going to be high compression(11:3:0) with a mild cam and 3K stall in my 13 Ram. Will be a nice daily driver with really good torque in a 4door crew cab, but it will also mean business to😅.
TigreLoko24. Your 331 will be awesome! We’re thinking with the mild cam it will be around 500hp at the motor and 600Ib of torque. Rebuilt because of finding a bad piston when doing the Hellcat top end swap.
I had no idea RHS heads flowed that well. For some reason I thought they were more on par with Ed Performers and some of the off-shore alloy stuff. Nice to know. Great tests, effective for delineating what kind of results your particular path could reap. Makes me wish I had lower compression, and, especially, the "disposable" income to boost my stuff. Last blown Mustang I had was not all that impressive, but probably the PO's combination of parts was to blame.
Have you , or have you ever thought to teach Mechanics in College ? I think you would be a great instructor , (because you're not boring) like other instructors. And I love the Ford stuff !
I would love to see an Explorer motor on the dyno comparing camshafts. The old alphabet cams are cool but I’m sure there are much better cams out there now to make max power. SBF rules.....!
He did that theory already. but hes only ever seen 2 split in his life. and one was built like the other that ran almost 9s back in the day why the second one broke? casting flaws maybe or a tuning mistake just that one time
Some interesting power comparisons Richard. I’m learning a lot. Would love to see some more oddball stuff (chev 348, Yblock, nailhead, Caddy V8 etc) with boost? That would be cool.
Hey Richard! So back in the day I built my first (and so far only) V8 for myself. It was a 306, Eagle rods, KB pistons, your favourite cam (TFS stage 2 224/232), Powerheads CNC ported E7TE heads, an Explorer intake, and long tubes flowing through a 2.5" Magnaflow exhaust. I never really developed it beyond the initial stage, it made 252/280 at the wheels, and since then I've wondered if I'd made a couple wrong choices that limited me. The TB was a 60mm and "I read" that a larger TB would only be worth a couple. The headers were 1.5" as I wanted to keep a bunch of torque, but maybe larger wouldn't have hurt. I also wondered how those heads were doing, if they were really capable of more or if I would have been better with some Edelbrocks (let alone the AFR 165). At the same time my buddy built his own 306 with the same cam but with bigger everything - ported Edelbrock heads, 1.625 LTs, a single plane and a 650 - and he made the same power as me but way less torque (no kidding) on the same dyno day. That made me think I was on the right track with mine... Whadda ya think?
@@richardholdener1727 Cool, thanks! I thought the heads would be reasonable given the CFM / CC numbers. Certainly not in the TFS/AFR category, but good enough for the snappy street engine I was hoping for. I just never knew if the AFR 165 would have been THAT much of an improvement... I guess so?
Great test. Now convert that bottom end to a BOSS 302 (347). This is an engine I'd love to build if I can ever get a car worthy of it. CHI 3V heads on a 347 stroker. Your previous piece on the 302 BOSS yielded great results. This is just going that extra step. Then add boost!!
I would like to see the comparison between a 358 Chevy inline valve NASCAR engine and a 358 Ford With Yates Cleveland heads. I have heard the Chevy makes more torque and the Ford makes more HP. The Ford is outlawed in some racing series and I wonder why?
I wasn't expecting the trade off of the low end to be that much. I wonder if the combination of a milder cam and the RHS 215 heads would of yielded more bottom end and still the same top end output. Appreciate the content.
Another great Video. Yes, More cool stuff!! Keep 'em coming! How about updates to low buck head test? I've never seen the Skip White NKB style heads tested anywhere, or the newer 3036 Speedmaster/Procomp head? AFR Enforcer 185cc? On a 306 or 331, how well do they work on a 408? Thank you! Can't wait for the next series of tests!
what happen to the impeller tips of the supercharger ?, 666HP that pretty much destroy the theory that this SBF can only handle 600HP. A question Richard, have you seen 347 with Aluminum rods ? they are always larger on the rod caps, is notching the cylinders still possible or the notch is so big that you have to notch the block pan surface as well ?
Hi Richard, thank you for your great videos. I am building a1984 Ford 302. I have the Promaxx 180 heads and I'm converting the engine to a roller cam set up. I am curious as to how the Mustangs would perform running a stock or mild Cam with this set up. I believe you will lose some power but gain driveability. Have you thought about doing any tests like that on the dyno? Thanks, Tom
Loved the vid as always. It's cool the way u do it and explain it as well. I wish I had u as my tuner. Can I ask so now at 666bhp to go past that will u need to do Forge pistons and so on . Plus it was 300bhp stock ish lol how did u no it would take that much on stock pistons. This build has got me hocked. Ok in the uk we run 2.0L and maybe 3.0 v6 . My wrx was 2.0L but ran 390bhp on stock bottom end. I been told most engines will take double the bhp so 200bhp 2.0L will go 400bhp . Can not wait for the next one. One more thing am thinking of gettimg a msd box to pull my timing. But not sure what one its a 4cy 1.8Tt turbo 2003. But all vids on utube so a msd box going to a distributor cap. So i don't no to get the 6msd or the msd6AL. Help
Awesome Awesome Awesome wish I had that last configured 347 in my 1977 Cobra II Mustang ! Love your Ford videos! Would like you to test a 390 they get no respect and they are awesome engines had a lot of them and always good power and super reliable. Had a 1967 Galaxie that would do 150 topend . Had a 428 police interceptor intake 800 cam carb and gt390 cam
@@PatrickScottlxw with a 363? Hell yeah its gonna be a big ass difference.. it can spin and its gonna always have an advantage because a 363 has to be made with a dart block because its 4.125 bore.
Hey Richard.. What you do with the testing of different components to see the results is a service to the community.. Thanks a ton.... Question.. Why stroke a 302 to a 347 when Ford makes a 351? 2nd question.. If you use similiar components on a 347 and a 351 would you get similiar results?.
Hey Richard have you ever tested running a roots style supercharger mounted remotely like a centrifugal supercharger. Could test the difference between mounting it on top of the engine vs off the side of the engine vs a centrifugal. Would having a manifold with runners make more power or would it make it change boost curve. Would be cool to see because you could run even bigger supercharger that arent able to bolt on top of that engine normally
How many times have, you used these combos, personally? twisted wedge heads... B303 cam was pretty good in that 5.0. ..... I know you love loved the Mustang, I had one also, best bang for the buck, I had 86 and 25th anniversary 89 and 1/2..fun Cars
By the way, my buddy split his block in half, launching on that set up with a 125 shot of nitrous!! So yes it does happen, not a myth.... Keep up the good work man!! I'm an LS man now, 2000 WS6 Trans Am, Still like the Mustang though, you can't forget your high school cars...
So i was at my local cars and coffee last week and met the organizer whos an old foxbody guy he was telling me that making a 450HP 347 is a kind of a waste of money because what he would do back in the day is get a stock 5.0 and put it on a progressive 225 shot and well, now hes caught up with you and your 1500.00 stroker kit and notched block and bigger heads lol blow it up. oh well, it was a 5.0 go get another engine all you had in it was the nitrous refills and tuning time lol makes me wanna either just stay 302 with bolt on or go 363W or make a 500HP N/A 347 any thoughts on that?
I’d like to see a back to back test with a similar setup to the 666hp combo shown here. But test 1 stock ignition. Test 2 typical MSD 6AL test 3 LS style coil near plug. Holley has made it pretty easy to goto coil near plug now, but is it worth anything at all vs the 1970’s MSD box ? Lol. I’m an LS guy, but I love the SBF stuff too.
I'm getting ready to put a roller block 351 together for a tow application, looking to go high torque. I have acquired a set of +p heads. I would like to keep stock fuel injection with upgraded throttle body, injectors and a tune. My question is am I spinning my wheels with this combo or should I go with aftermarket heads and intake? Also what cam would you suggest for this application? Thanks, love your videos, learning so much.
i'd like to see a stock 2 bbl 302 run on the dyno...then just add a stroker for 347 cubes and run it again and see what power the stroker will make like that ...and i still wanna see some y block stuff
Richard have you heard anything about the TFS twisted wedge heads bring used on a 347 combined with the pro charger using the same cam combination the you used in this video
Stock 5.0, stock aluminum 4 barrel intake vs, torker, performer, performer rpm, performer rpm air gap, Victor jr., TRI carb, and tunnel ram. Just for fun.
Like to see try y headers vs others. All so like to see how the offenhauser duel port intake performs as well as the offenhauser 360 split single plane. Would like to see a super tall 4 hole carb spacer say 8 plus inches tall on a duel plane . All so like to see a tall 8 in+ tall 2 hole spacer on a duel plane. My idea is to make a engine with a broad power band with a lot of low end. Love to see a custom intake that could out do the rpm air gap! Has to be a carb intake.
How much power can you weasel out of a 302 HO sbf with a stock cam, and no supercharger....? For us guys with an auto and tall gearing that value gas mileage....
Not much more than stock. Intake and headers. Better off putting in an rv cam for about 300hp. If you want 400hp you need bigger cam, higher stall converter, and rear gears. Aluminum heads will make more power with less camshaft. Low end torque will suffer though.
*** HELP *** RICHARD HOLDENER *** WE CAN'T READ THE NUMBERS ON THE LEFT OF YOUR DYNO GRAPHS, RICHARD!!! COME ON, DUDE!!! WE LOVE WHAT YOU'RE DOING, BUT WE WANT TO READ THE NUMBERS!!!
I am not a fan of the 347 architecture because I'm concerned about the piston speed and the side loading of the piston in the cylinder. Won't those two factors cause the engine to wear much faster than a 331 or stock 302 stroke?
Am I the only one that can’t read the power numbers on the left?

Can you do a junk yard (or aftermarket) 351w 427 stroker or a 408 stroker? With the same mods ie boost / cam /heads

By the way, my buddy split his block in half, launching on that set up with a 125 shot of nitrous!! So yes it does happen, not a myth.... Keep up the good work man!! I'm an LS man now, 2000 WS6 Trans Am, Still like the Mustang though, you can't forget your high school cars...
I've run the 5.0L stuff 1000s of times
So i was at my local cars and coffee last week and met the organizer whos an old foxbody guy
he was telling me that making a 450HP 347 is a kind of a waste of money because what he would do back in the day is get a stock 5.0 and put it on a progressive 225 shot and well, now hes caught up with you and your 1500.00 stroker kit and notched block and bigger heads lol
blow it up. oh well, it was a 5.0 go get another engine all you had in it was the nitrous refills and tuning time lol
makes me wanna either just stay 302 with bolt on or go 363W
or make a 500HP N/A 347
any thoughts on that?
We cant see the power numbers on the left side of the screen.
I’d like to see a back to back test with a similar setup to the 666hp combo shown here. But test 1 stock ignition. Test 2 typical MSD 6AL test 3 LS style coil near plug. Holley has made it pretty easy to goto coil near plug now, but is it worth anything at all vs the 1970’s MSD box ? Lol. I’m an LS guy, but I love the SBF stuff too.
Good morning Richard can you ever do a test with explorer gt40 heads?
Have you looked at his other videos?
What's the go with that blower impeller, surely that's not an actual picture of the one your using ?
I'm getting ready to put a roller block 351 together for a tow application, looking to go high torque. I have acquired a set of +p heads. I would like to keep stock fuel injection with upgraded throttle body, injectors and a tune. My question is am I spinning my wheels with this combo or should I go with aftermarket heads and intake? Also what cam would you suggest for this application?
Thanks, love your videos, learning so much.
the P heads would be better than stock, but not as good as TFS or AFR. A cam is a good idea
Stock injectors will need 43 psi or probably a size upgrade.
@@richardholdener1727 by any chance could you recommend a good RV cam or on the upper end of the RV cam range.
i'd like to see a stock 2 bbl 302 run on the dyno...then just add a stroker for 347 cubes and run it again and see what power the stroker will make like that ...and i still wanna see some y block stuff
Could you do a 5.9 magnum NA intake manifold test, efi and carb
Gotta fix the showing of the horsepower numbers on the dyno sheet,its driving us crazy Richard.
I'm working on it-not sure what the heck is going on
Ford v10
Please fix the power numbers on the left so we can read them. Thankyou.
How changing rocker arm ratio affects performance
I thought the torque curve dip from the dyno tip-in was irrelvent for that first 300 rpm.
So is it, or isn't it?
The head item number, thanks...
Richard have you heard anything about the TFS twisted wedge heads bring used on a 347 combined with the pro charger using the same cam combination the you used in this video
that combo would work fine-I ran a 347 with TW heads (as cast and CNC)
Stock 5.0, stock aluminum 4 barrel intake vs, torker, performer, performer rpm, performer rpm air gap, Victor jr., TRI carb, and tunnel ram. Just for fun.
take a look at the video comparing the perf, rpm air gap, torker and vic jr.
What pulley size was that again? Looked like a 3.15.
Also C/R? I presume 10:1 on why that thing was over 600 and rising.
If you couldn’t have the final combination, would you rather have the booster “stock” motor or the modified NA motor?
I would get cheap Explorer P heads and a cheap cam then add boost
Like to see try y headers vs others. All so like to see how the offenhauser duel port intake performs as well as the offenhauser 360 split single plane. Would like to see a super tall 4 hole carb spacer say 8 plus inches tall on a duel plane . All so like to see a tall 8 in+ tall 2 hole spacer on a duel plane. My idea is to make a engine with a broad power band with a lot of low end. Love to see a custom intake that could out do the rpm air gap! Has to be a carb intake.
Word
Another great video
What percentage of driveline loss could you estimate in a foxbody? T5, 3.55 gears, 17” wheels, roughly stock weight.
I would like to see how much more horsepower a stock 302/347 block would hold with a girdle before it splits the block.
THAT DOESN'T REALLY HELP WHERE IT SPLITS
I wonder what a motor like this will do whit a budget eaton m90 supercharger.
How much power can you weasel out of a 302 HO sbf with a stock cam, and no supercharger....?
For us guys with an auto and tall gearing that value gas mileage....
Not much more than stock. Intake and headers. Better off putting in an rv cam for about 300hp. If you want 400hp you need bigger cam, higher stall converter, and rear gears. Aluminum heads will make more power with less camshaft. Low end torque will suffer though.
*** HELP *** RICHARD HOLDENER *** WE CAN'T READ THE NUMBERS ON THE LEFT OF YOUR DYNO GRAPHS, RICHARD!!! COME ON, DUDE!!! WE LOVE WHAT YOU'RE DOING, BUT WE WANT TO READ THE NUMBERS!!!
I am not a fan of the 347 architecture because I'm concerned about the piston speed and the side loading of the piston in the cylinder. Won't those two factors cause the engine to wear much faster than a 331 or stock 302 stroke?
The 347 has been out for a long long time now, and those questions were answered quite awhile ago.
stop worrying-if you build it-the power will come!
