HOW TO: BIG HP 408 STROKER FORD!

[@cuzz63]

I like that statement.."if it makes more Tq than Hp there is still more performance to be gained"...

[@albertgaspar627]

it is the truth. along with, "HP sells engines, Torque rules the street" :) If you want MPH at the strip, build for HP. If you want to chop the seconds, work on torque and launch to win at the starting line. For the street, focus on torque at low RPMs, and get the gas mileage for "free"....and use junkyard OEM parts to do it with.

RPM Air gap is known to make a lot of torque! It's a good design. It was cool to see the TFS single plane had almost the same peak torque and simply shifted the curve to the right by 1000 rpm.

[@jamiemuncy2219]

BW MadDog [retired] you see the picture icon by my name? That was a stock block 393 that accidentally made 1500hp and we didn’t know we were getting bad data we had a short in the data logger and well she split😱👀😝

[@albertgaspar627]

For every success story, there are others where someone found the "friday afternoon" or "monday morning" block. In the old days, folks worked with what was in the junkyard, but today a Dart 363 block that can go out to 440 cid is easy enough to obtain. I know its cool to gamble, but I can't dump money into machining, girdles and Hard Blok just to have it pop like a pimple in a year--its never cheap when you do the job twice.

[@jamiemuncy2219]

Albert Gaspar I agree I just worked with what I had and budget but today it’s grown into a 468cid Dart Iron Eagle block monster that on motor made 1500hp but I’m in the process of switching to twin 72/74 or 76/74 I’m not for sure yet.

[@albertgaspar627]

Yeah, i should say, everyone's free to do what they want and racing is expensive, but no one loves the racer who oils down the track :) As for a street engine, there's no E85 around here and so that means $12 a gallon for anything over 93 octane. If I want to make big numbers and not just toss together leftover parts (nothing wrong with that, its why i keep buying cheap parts for the day i get another car that will take 'em all) for the street, i'll go big on displacement and then a power adder...that typically means more off-idle torque and with a roller cam (with steep ramps that shrink duration like the old variable duration lifters but give a higher redline than those flat tappets), less need for boost but a real focus on valve springs to keep the valves following orders. Until I hit the track and can dump the gas for 100 octane and then crank up the power adder. That's my take on it, maybe others have even better ideas.

[@jamiemuncy2219]

Albert Gaspar I’m a solid lift roller cam kinda guy with big lift with a REALLY BAD ASS CHOP that beats the ground but makes big power where it counts...middle of the run and on but I like enough to get you off the brake. The cam I’m running now is a Crower special grind duel pattern in the 880s & 890s lift. That’s where you run into spring control problems but my dads best friends with an old IHRA ProStock champion from the 80s and he built his own engines and still has a machine shop and he helps us with all our head work. Doug Kirk is his name & he’s a under study of Bob Glidden so I’m covered on all my heads and intake stuff lol I’d love to find me an old RDI block, those take some abuse 👀👀

[@hardball107]

OMG, I love your videos. I've been trying to tell people for years that on a larger motor with a serious cam a single plane is the way to go. If your running a small block engine you might want to run that dual plane to enhance the torque down low where you do most of your driving but with the big inch motors making 300-400 ft/lbs. down low you'll just spin your tires. Better to soften up the motor down low and let that sucker eat up high. Thanks much for this test, now I have something to show those folks that read to many magazines.

Lets see where that 351W roller block sits on the strength department. Got my hand way up! Good series of dyno tests to show what happens when you have one of the combo too small. If you're looking for good torque for the street there's no doubt the RPM Air gap is the way to go. Need more top end? Maybe could have put an open hole spacer on it, maybe even a 2 or 3 inch spacer just for the track? Again, thanks for posting! Nice vid!

[@danmyers9372]

I continue to be amazed at where the little 351W stands today as a performance engine. In 1973 I purchased a used 1970 Mach 1 with the 351W. At that time there were basically NO companies providing aftermarket speed parts like heads and cams. About all I could do was add a mediocre dual plane intake, 700 Holley and headers which didn’t do much to help the anemic 250 (GROSS) HP factory rating. The Cleveland small block got all the love back then. The 351 Windsor was considered a “truck” engine not unlike the 390 FE. Oh what I would have given to gave had an engine like in this test. I would have been king of the streets!

Please do much more 351w testing! This was interesting to me since I run a nicely built 408w NA for road racing. It's a solid roller motor with .609 total lift from the custom cam and has the exact same 205cc runners on my RHS heads. I've been a little worried to rev it out to 7k like it was intended from hearing about main cap walk. Any experience with the RPM limits of these factory late model 351w blocks?

[@lloydholt6511]

Great test. About the time I thought “ I wonder what a 0.620-0.650 lift cam with a little more duration would do for this combination.” Yo came up with the stouter cam you run. Another test with more compression ratio( around 12.0:1) and a fogger system would be interesting Of course a turbo or centrifugal compressor with at least 25 psi boost would really tweak the ears on that Ford. As always thank you for making us think. I really enjoy your videos.

Was a bad ass engine. Really helped with torque down low. Also helped with torque up high as well. I’m pretty sure it made around 450-500hp and 500-550 torque. Would still rev to 6250 no problem, didnt ever let it run out that high too much because it was an all cast rotating assembly.

Often with multiple vastly different weights for the same engines in the same list. Other than that, you keep answering almost every engine based question I have ever thought about ! Here's a few engines that I hope to see you take on; 3.5 litre Buick/Rover aluminum V8, Ford Barra straight six, and the Ford 4.9 (300) straight six. The 4.9 might be hard to find . . .

You need to add that a street motor wants more tq. Even at the beginning of your dyno run it is making good tq. That engine for the street is a good strong safe street engine.

It would be nice to show that the old 351 can still hang with any of the LS Combinations. Its such a versatile engine, and can be built to make so much power. Not to mention its going to be lighter than a big block. I only wish Ford would have continued the production of this engine, and developed a factory aluminum block, similar to the Teksid 4.6 block.

[@mikeglick3507]

I love your posts and have watched many of them. The one constant thing I see is more power, but it is just moving the power higher but down the RPM range. This is great for track cars, but for street cars this is making a less street friendly car. You should talk about rear end gear ratios. You are loosing low end torque for horsepower. Torque makes the car move, horsepower takes over once the car is moving. Now there is a need for a stall converter or in the case of manual transmission higher revs to leave a stop light. For every action there is a reaction. I think that many less experienced viewers will not understand the relationship between the loss of torque and the gain of horsepower. Please explain this in your future posts. Thanx!

During WW2 They boosted Mustang fighters with NOS. They also tried hydrogen peroxide which had power levels that were close to the NOS systems. Problem was it was highly corrosive. Today a lot of hot rodders are running water/alcohol injection on turbo and supercharger systems to fight detonation so they can run pump gas and high boost.. I wonder if replacing the water part of the mix with 35% food grade peroxide wouldn't be another power adder no one would ever suspect?

Take 2 5.3’s or 6.0’s one with dish pistons one with dome or flat top pistons, have dish piston motor run stock heads unmilled, then run some milled heads on the dome piston motor, run a stock cam in each one, then throw in one of your famous cams in each one.
