- FULL DYNO RESULTS. MILD 347, THEN BOOST, THEN MOD, THEN BOOST. WHAT HAPPENS WHEN YOU ADD BOOST TO A MILD 347 STROKER EQUIPPED WITH STOCK 5.0L HEADS AND CAM AND GT-40 INTAKE? THEN WHAT HAPPENS WHEN YOU UPGRADE THE HEADS, CAM AND INTAKE? THEN WHAT HAPPENS WHEN YOU ADD BOOST AGAIN TO THE MODIFIED MOTOR?

Am I the only one that can’t read the power numbers on the left?
It’s been the last few videos.
Richard Holdener
We cant see the power numbers on the side bar. None the less, you are a dyno master.
Yeah, I cant see them eother!
It's making me crazy!
@@Cowboy.underwater Maybe hes doing it on purpose to see whos paying attention. Like how I was paying attention to the chunks missing from the impeller fins on the supercharger. Gotta round up or down that 666hp number though lol...
I can’t see it either
@@nova467spanker Unless the motor's going into a Demon
Thank you for remembering us ‘old skool’ sbf guys Dr Holdener. 👍
Richard, on the last couple of videos I can't see the y axis on the dyno chart.
s1lv3rz
Me neither
I've always wondered what a 347 with stock heads and cam would do. Keep the Windsor stuff coming!
340 am can't sleep just watched the mishaps with the 292 points and saw a few other videos and now I'm watching this Richard you are awesome
same
That addition of heads, cam, and intake was wicked. Totally transformative. Holy crap.
I'd like to see a stock 2v Cleveland with a turbo(s). Then the usual heads, cam, intake, etc. Thanks for another kule vid.
Thanks guys, great comparison between the two. This will help me with my 347ci build.
Hell yeah man, stroker sbf+booost+dyno #’s Thanks for the tests richard! 👊
Great vid!!! This was pretty much the progress of my current combo, minus the stock block and lack of meth..
This vid is right up my ally only differents is using a Weiand low blow unit. great info great vid takes some of the quess work out thanks Richard !
Can’t wait for the junkyard 351w again love the videos 💪💪💪
I LOVE IT!!!!! THANKS FOR SHARING!!!!! I LEARNED SO MUCH!!!!
Still waiting on the early model 429 Ford you showed a couple of weeks ago. Lovin' all the testing!
Thats alot of power! nice video
Awesome vid. Makes sense how I could run/pull sc fox. Most prob just had sc and gt 40 intake and or cam 👌🏼👍🏻
Thanks for this video. I am building a 347 right now, I have all trick flow ups so I hope I can make the same power
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.
I’d like to see that same test with a 331 stroker SBF and compare it to the 347.
HUZZAH to the most prolific and best content bloke on youtube !!
A truly devilish motor!
Love your content Richard. Eagle Hemi stuff would be good fun.
Thank you Richard
MORE Ford 400M CONTENT......Please
Another great morning video
Can you do a junk yard (or aftermarket) 351w 427 stroker or a 408 stroker? With the same mods ie boost / cam /heads
he did a junkyard 351W
broke a piston on boost at 1000hp because he didnt gap the rings
Another great video
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!
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
"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.
I think a similar test with a 393 or a 408 would be awesome
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.
Joe sherman said they are between eddy and AFR
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
Forced induction is the way to go!!!!
Would like to see some PD twin screw boost tests. For us with DD that are mostly street driven.
Great video
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
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.
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!!
3:22 looks like a mouse chewed on your impeller blades! I hope your test wasnt done with that busted unit?
I said same thing bro. Those blades are shot lol. We know Richard tho. If it works, chances are he's gona still use it unless it's detrimental to the engine.. thank God we got this guy tho for real
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.
the iron rings are best-cuz minerals
Philip Ball : Squirells. The Mouse is normally in side a small block Chev.
Bearings good? Oil seal good? If so, good chance he ran it.
Heat treated impellers will take a beating.
On the hyd lifer motors what preload do you use? 1/4 1/8 1/2 Thank you keep up the Ford work.
Its nice to see that the torque stays flat after modified * boost
By the way, thank you for the great video's
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.....!
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!
we had a plan like that for Wheel of Death
SBF have FIVE mains.
HotRod Ray really? Are you sure?
Right on
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😅.
@@bri-manhunter2654 Man thats going to be nice!!!
to me bigger is always better, but that 331 is obviously better than the 302, its gonna be a fun daily, bro..
@@bri-manhunter2654 sweet, i love stroker motors, dyno it..
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.
Great video, I would like to know the Compression ratio on the engines before adding boost.
near 10
I love the damaged compressor wheel
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’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.
Could you do a 5.9 magnum NA intake manifold test, efi and carb
more 4 bangers
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)
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.
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!!!!!
there is a story about the wheel-and don't EVER say an unkind work about the 224/232 cam! lol
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?
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
having the long-runner intake would help with a remote mounted roots blower
Wow Richard, that is a very sad looking compressor wheel at 3.23, did Road Kill loan you that from the “she’ll be right collection”
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?
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
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.
A BETTER HEAD CHOICE LIKE THE AFR 165/185 OR TFS 11R
@@richardholdener1727 Is that because of the better flow characteristic at lower lifts?
crazy how low of cfm the stock 5.0 heads really can flow. Just for reference, most refrigerators flow 350cfm lol.
Tried True and Ford Blue!!! 👍🇺🇸👍🇺🇸
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?
those heads-even ported aren't great-the Explorer intake also limited power-cam was good, headerd are fine
@@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?
Now I'm going back through my copy of "5.0L Ford Dyno Tests (by Richard Holdener)" for nostalgia... man, look at you with hair!
How changing rocker arm ratio affects performance
Hey Richard, have you ever done a back to back comparison of the old Ford Motorsport letter cams? Thanks!
Theyre ok, but they are 25 yr old grinds.
Modern grinds with modern springs do notably better.
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?
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?.
yes similar results-I would chose the 351W-it has a stronger block
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.
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.
What percentage of driveline loss could you estimate in a foxbody? T5, 3.55 gears, 17” wheels, roughly stock weight.
Do a episode where you push a 302 block to split that would be awesome
I'm a Ford guy and even I'd love to see that
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
@@KingJT80 I know he did that, but I actually want to see it happen lol
@@TheTeeroy32 well we know it wont last till 1000hp like the 351w did
Wow look at the power curve with the blower it just keeps going and going, would probably peak out around 7500 if you let it 🤔
What about a carb blow thru vs draw thru turbo comparison.
Would like to see you do a AMC engine
Oh man... Now you did it
Donnie Coleman : x elent. We have foresen it, Darth, um, Mr Coleman. :-)
Good morning Richard can you ever do a test with explorer gt40 heads?
Have you looked at his other videos?
High compression stroker big block ford. Plus head comparison low buck vs. high buck.
Well there goes that block splitting 600hp theory
Hi Richard, you need to name this engine the BEAST, because the 666 is the mark of the beast.
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...
I've run the 5.0L stuff 1000s of times
I'd like to see the 347 compared to a 351w with similar mods.
They; be about the same. a junkyard 351w he did with the edelbrock top end kit which has a cam about this size made 450
FORD POWER BABY !!!!
Richard, did you ever, or could you in the future, do a smog legal test on a 5.0 stroker? Say AFR EO# 165 heads, a Crane 216* EO# cam, JBA EO# shorties and a ported Explorer intake? All on a 331 or 347? And then add Pro Charger's EO# 14-psi blower?
This is what I had on mine without the blower. I also had an E303 cam. I made 327 on a mustang dyno. 430 with a little bottle shot. Kept it all street legal because of California smog. Was a lot of fun.
Now dropping in a Boss 302 block stroked to 342 and a turbo. Should be fun.
Time to test some Aussie stuff , how about a barra or an AU 4.0 i6 vct
What compression did this configuration have?
We cant see the power numbers on the left side of the screen.
What's the go with that blower impeller, surely that's not an actual picture of the one your using ?
No love for the gen II LT1 or a stout SBC AFR headed 383? 😢😔
Go look at his other videos
Camaro_LT1 : Plenty of Chevy LT1 "Luv". Weekends spent incinerating tires and Ford egos. Mine...
Big Bang 454....🙏
How about a stroker 440??
After you posted y'day
SME posted a tt small Ford that makes 15+
Everything is better w some boost
How about boost and nos together
Bwahhhhhh!
Word
Richard, I noticed the blades on your supercharger are chipped on the ends. Are you aware of this?
just the photo-the Paxton blower (in the photo) was damaged, we replaced with a Vortech for the test
What fuel is used during the dyno pulls? 93 or 91 octane or E85, race gas?
91 for pump, e85 and other race fuels
If you had a '65 Mustang Convertible just for cruising/street rod use...
What engine would you pick?
BTDT
Stock 5.0 HO fuelie with T5.
Simple, easy, efficient, powerful.
Stock will kick a 289 HIPO car into the ditch.
Ive done several.
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
Hi Richard, I’m building a 347 stroker with a Dart shp block. I have a set of afr 185 heads 58cc. My question is, if I’m running a turbo, can I use these heads or do I need to upgrade to a bigger head for 900 horse?
THOSE R FINE
Thanks Richard
Can you test a 347 with afr 220 heads and a 75mm turbo. The cam is 590 is lift and 114 lobe separation, and 65lbs injecters?
the 75mm turbo dictates the power potential
@@richardholdener1727 it's the combo I'm putting together in my drag car
