Great video for us SBF guys. I cannot imagine what that Boss 302 with 102 LSA sounds like. Would love to see/hear that pull.

Man this is simply the best and most charitable Ford small block build content on all of KZfaq. If I had the slightest clue on how to do this stuff to EFI systems on my 94 lincoln then I’d have the engine apart in my friend’s garage within the hour.

+58 hp on the 363 going from 170 as cast to 210/220 cnc ported heads was impressive!

I love this channel 👌👌👌

150,000 mile stock 92 5.0, 62mm Hellion kit with 42 lb injectors, a Cobra intake, 1.7 rockers and a single 3.5 inch exhaust. It make 444.6 HP at 4,800 rpm and 537.8 lb/ft of torque at 4,000 rpms to the wheels. It lasted for 6 years before the oil pressure started to lay over due to bearing wear. That was a fun combination.

Boss 302 so frickin awesome!!

Now.. after watching this.. I took what I hope to be 400hp engine combo and threw it away..starting over!😎☕🎬🏁

Please mention the compression ratio on the different combos. Thanks, keep up the great work.

Still love the look of the mini charger. That never gets old.

Wow, that turbo setup would have taken ages to assemble, no wonder you ran out of tuning time. As always, your videos are fabulous, thanks for all your hard work, I can’t imagine how many people you have saved from making up dud combinations. Luv the baby Boss, that might be my next build, I’ve never seen one in the flesh, no idea what cars they were ever fitted to, we usually just went 5.8 Boss. G’day from down under.

Great video Richard, you have some of the most informative videos on KZfaq as far as I'm concerned. I'm getting ready to build a 351W based N/A stroker combo for my '70 Mustang street car.

Thank you for all your efforts sir 👍

Junkyard turbo build for the win!

95 302, B-cam (I think) Pro Topline 180's TFS intake, 1 3/4 headers, Vortech V2Si (IIRC) 453 to the wheels.

Awesome job Richard! Keep up the great work!

Im loving the turbo set ups, my stock 88 5.0 with victor jr intake and quick fuel 750 blow thru made 454/510 wheel on 15psi ran a best of 6.76 in 1/8 so i was happy with it

That 347 with those cnc brodix 210 heads on it must have had low compression, because with that set up that engine should have made 500hp without the nitrous. That is a healthy cam, and some really good heads, vic Jr. Nice 650 carb, 501hp all day.

This is awesome Richard I have a 5.0 efi in my falcon with gt40p heads bigger springs and arp studs running a gt45 ebay turbo on a custom manifold can't wait to get it on a dyno then change from the stock cam and see how much I pick up

waiting for the 800-1000hp 351w combo

8👍's up guys thanks again for taking us all along with you for the great show

I liked them all!!!!

Surprised at some of the hi valve lift figures Some very interesting tests. Thank you for the SB Ford stuff.

Up next we modified a yogo motor using fiat berton head and turbo custom camshaft arp rod bolts and propane !..lol i would love to do that to a yugo gvl 4 banger lux modle

The CHI heads are impressive-a future video, 1000HP Boss 302 with turbo? Thank you Richard.

No 351w love? I guess those will be in the 600 hp edition.

I like the tubo setup. That torque curve

That 363 combo with 568hp is what I love the most!

Loving the Ford stuff, thank you! 351 with gt40p heads and a 266hyd roller cam is what I'm putting in my 83 I think. Have a preference for 460's but, man a junkyard roller351 would be so cheap and easy to build.

Wonder why no one has thought to integrate a carb or injection system right into a supercharger? A nice clean one piece unit would be cool.

Really enjoying this series. I have a 5 litre Tickford Windsor, a 220kw version, in my Land Rover 101FC and hoping to upgrade it a bit in the near future...

I ain’t scared yet. lol. Would love to feel 500hp in a mustang. Or a w3 trans Am. I heard it’s a lot of power. Holy smokes Richard!! Thanks for your awesome content and huge efforts every time.

Right on

Hey Richard Even though i have a lot supercharged stuff[coyote] ,i love the n/a on dynos,boss 302 was impressive,i would like to see the 363 dart with chi heads and a healthy solid roller

That boss 302 is awsome, bet it sounds nice screaming on the dyno. The turbo junkyard stuff is more relatable..

Just for fun or budgetary issues: Les Schmader cleaned up my '70 B302 heads...no enlarging or polishing...and the numbers are interesting when comparing to the CHI #s as prepped by Dr. J's. For whatever reason, Les didn't check the flow below .200 lift. One thing different is that I went with slightly smaller intake valves than stock...2.125 vs normal 2.19...just to see if there was any difference due to potentially less shrouding. Didn't seem to change anything significantly that I could tell. @ Lift Int Exh .200 158 105 .300 220 154 .400 264 189 .500 295 205 .600 320 210 .700 335 212 The velocity is surely much better on the CHIs, and the exhaust flow is significantly "better", but if you have some old big port/big valve canted valve Ford heads, it takes very little in the way of cleanup to make those iron lumps flow pretty well. And it would be budget friendly to just clean out casting ridges and flash rather than buy some pricey aftermarket heads, as long as the originals didn't need serious work or all-new everything.

363 is the one!

Mo Powah Baby!!!

HOPE SOME BIG W STUFF ON THE NEXT VID THX FOR THE FORD STUFF

Been thinking of what to run on my old f100 I Kinda like ghe junkyard 351 with a turbo idea

more cleveland stuff. also do 2v-4v-3v comparisons on the same motor pleeeaaase!

Pick a favorite?? Hmm, tough question.

You need to do a 351 Cleveland, but this good stuff!

Gota get my fix

A steel vs aluminum rod test would be cool

I want to see that Vortech maxed-out.

Richard please do a 5.8 whit ruck effie intake and turbo

Richard Holdener Speaking of limits of stock parts, have you found the limit of the stock fuel rails? Is it something worth spending money on or not?

hmm... we got an f100 that's been sitting for a good 16 years... I wonder what the 1974 393ci would run as is? was only ever used to plow snow and take in the recycling. That block costs more to replace then a regular used running 5.3

The nitrous fed 347 says ProMaxx 210 CNC heads in the description but you said Brodix which one is the correct? I'm guessing with the power produced it is the ProMaxx heads because I think the Brodix would be doing better than 441hp.

I thought it is going to be all stock block 302 builds. Oh well. , thanks good video

Hey Richard. I watch all your videos. Good stuff. I have a question about nitrous and ring gap. Which rings do you gap and how much for nitrous. Probably just a 250-300 horse kit

I dont know but have you done any back to back testing with Roller VS Flat tappet cams with equal advertised duration to compare roller profile gains? Perhaps a thought for another series?

What if you put a 225 head on a 306 running a novi 2000 how would that react?

Nice to see the BOSS make some power! Can you PLEASE do a 289 video... Something old school with 13.5-14:1 with a Custom ground solid roller like from Cam Motion & show these youngsters a 8000rpm Monster? Thanks for another great video!

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, will power output increase if any.......

So what's the best way to get 400 hp on my 95 mustang gt pretty much stock. Mods:Cold air intake Exhaust: stock headers, off-road h-pipe and flow masters out. Driver:Me lol

That's what she said... Compare the small head to the big head that's a good 1 🤣

didnt start out with good head but finished with really good head...... lol

Sorry I totally missed what the compression ratio was on the Boss setup. Just goes to show it's all about the flow.

Throw that paper weight of a funnel web intake in the scrap pile. Every time you run that intake it just sucks lol gets you the peak hp numbers but no real usable torque under 5000rpm

Richard, wondering what you'd think of this combo - a 5L roller block, bored .030 over, fitted with a set of approximately 8.5 to 1 compression forged flat top pistons set at zero deck height, some good aftermarket steel rods, a set of mildly ported TFS 'Twisted Wedge' heads,. a Comp Cams XFI1236HR or similar spec high lift, medium duration roller cam, a good single plane carburetor-type intake but instead of a carburetor, set up for EFI with a 70 mm throttle body and plumbed for fuel rails and port injectors, a pair of shorty 'block hugger ' style headers with each header feeding a low mounted T3/T4 .60 A/R hybrid turbo (-ie - one turbo per side) which would then feed a large front mounted air to air intercooler?

I’m putting together a 347 for my 89 bronco I have a speed master stroker kit, minus pistons, it’s a cast steel crank and forged rods, I’m planning on an “rv” cam or something close to it, I wanna make 450-500 horse but manly want low end power would the small 174 blower be to much for the thing, I don’t wanna split the block or hurt components every other month, it’s getting a zf5 speed and 35 inch tires on 355 gears

Richard when you get the 351 from the junkyard do you replace the main bearings rod bearings in the rings or do you use the factory stuff?

@Richard Holdener might be a stupid question: do dome pistons increase blowby due to their shape, deflecting the deflagration to the skirt instead of sharing pressure in a more uniform manner?

Boss

Hello Richard,I am not sure how to send an email but here is a short talk ok..? I have a 429 I had put in my 78 ford ranger F-150..I know it was built in 96' because the motor the was in it was a 400 which the motor lost oil pressure and just was weak .Well I love my 429 but was wondering what I needed to do get more power ? I not writing every thing on here because it would be a book .. If you dont have time I understand ..Thanks for your time.

When you say add ring gap, what do you gap them at?

Would have loved to see a 408w with mild cam (15-17 in vacuum at idle) with good heads. Total street motor

Curious as to why the reason for starting the nitrous so late?

I'm actually very impressed with the HP/l on that BOSS engine. You bested 100HP/l, beating BMW. Do you think you could have gone over 600HP with that motor and a different cam with a HP peak at 8,000 rpm? That would have equaled Honda's best specific output of 120HP/l.

I'm thinking a 351 Cleveland with those CHI heads has to go way over 600 hp, or maybe a 408 clevor !!

Can a .700” cam be reliably driven daily? If not, at what lift does reliability diminish?

Wouldn't be afraid to run the stock explorer TRW pistons with boost?

Serious Question were you told to back off from the Coyote 5.0?

392 w

So did you test 210 vs 225 heads on this engine, or is the idea that the "210cc and 225cc heads make identical hp" an assumption based on different engines dyno'd in the past? Unless the 210 and the 225cc heads actually have the same cc runner, you can't assume that they are going to make identical power on every engine. Doesn't matter how many you've dyno'd and gotten that result, physics tells us this isn't possible on every engine.

Try some Nissan stuff man please

I like them all , but they all have different characteristics . A daily driver with a huge cam , isn't very practical .

Not ls! 😃

I kinda want to rub his bald head for luck.

Personally I blame squirrels

Those CHI heads are awesomesauce. Love to make a 408 twin turbo with those or P38's.
