The part 2 of this video is up where he bolts on a ported tunnel ram.
I'm anxiously awaiting the Street Dominator part 3 installment.

He had a small block in his 68 Barracuda bracket car. He built this 400 to go in it. And yes, he's 1/8 mile in Arkansas. Aha, thanks for that. That's not the dude I was thinking of, then. The youtuber I was thinking of had either a Dart or a Valiant, and his test track was something like 800 feet or other odd length.

I have speculated that any 400 using a 3.52 stroke crank would be a very good match for a torqueflite equiped bracket car. The short stroke will allow consistancy , yet at up to 426(!!) Cubes still make serious power, enough for a 10.00 et 3300 lb car. Easy to drive, as dhifts won't be too soon on the 1/2 given a good gear choice.

Dwayne Porter did a pretty straight forward 383 that made 500 hp. I have been able to duplicate it and it makes for a great 7.00/11.00 combo at #3400. However, I would that say that due to parts availability I'm not sure I would build another 383 but move in the direction that has already been mentioned- 400 based 4.375 bore/6.800 rod/offset ground 383 crank. http://www.moparts.org/Tech/Archive/bb/25.html
'75 Plymouth Duster Phase I 451 906/590/2-660 10.75/126 Phase II 451 Stage VI/590/1050 9.82/135 Phase III 383 906/Victor-Pump gas 11.30/119

With big block strength, and a stroke shorter than a 350 Chevy, how can these things not rev to the Moon? How high it revs will depend on the head flow and induction along with cam design. The short stroke and long rod ratio make the 400 gentle on it's guts at high rpm's even with heavy pistons and rods. Given the same basic induction and cam a small bore long stroke 59 383 (4.03 x 3.75) will rev higher than a .030" over, stock stroke 400 before it runs out of air, it's the overall cubic inches that draw a given amount of air, not the stroke.

It's fun to see a Mopar build out-perform what people think it should be making.
I see all these high dollar Indy Cylinder Head builds that Indy puts on it's Facebook page and it seems like they are all underperformers.

justmoparjoe did a dyno test recently as a part of this series on the Edelbrock RPM Performer but the Holley Street Dominator had a lot more power.

My favorite motor build I have even done is my 400 based 470. It's a mild street build. Ported eddys by D Porter, .540ish hydraulic roller, RPM Performer. That little motor is surprisingly a little powerhouse. RPMs like a small block. I would love to do a current version. With 240 Trick Flows and a little more cam. I am building a 470 now with trick flow 270's and a mechanical flat tappet. I hope it works well.

I see all these high dollar Indy Cylinder Head builds that Indy puts on it's Facebook page and it seems like they are all underperformers. While I have to agree the numbers on alot of them don't make them appear to be world beaters, some of those have been pretty helpful and encouraging since there was really nowhere else to find anything like a dozen 572 Hemi builds intended for the street, with really deliberate compromises, to study and then go talk to the builder about at a show. I'd thanked Kenny for putting more specs out there on the magical book of faces, as it helps guys like me out quite a bit... and he said it was Indy ownership's idea, they wanted no secrets... which is a very different business strategy than alot of others doing Hemis.

That little motor is surprisingly a little powerhouse. RPMs like a small block. I would love to do a current version. With 240 Trick Flows and a little more cam. I did a similar street build using OOTB Eddy heads and a street solid roller. !0.2:1 compression.Same intake and a Holley 800. I always say...it RPMs like a chainsaw and pulls like a freight train. It made 425 whp at 5500(could have easily spun to 6500) and over 500 ft lbs all the way up there. It lives in my 69 B'cuda with a 4 speed and 3:73s. Thing's a blast to drive!

I've been watching justmoparjoe do a stock stroke 400 build on youtube. Nothing special, 10:1, E-Street heads, Holley intake, 850 cfm Holley. He took it to the dyno and it made 530 HP? I was impressed. This is the dyno episode but the whole build is on there somewhere. https://www.youtube.com/watch?v=cEHE-_Zho-M&t=2s We made that much with an Eddy Head 340+.030 mild street engine. Care to share the details on your 340 build? What cam did your run?

Calling this build Cheap is not accurate although compared to a full on race engine I guess that would be so. One big staple of an affordable build is the cam and lifters. The option of reliable flat tappet cam and lifter sets is pretty much gone which is a shame. Back in the day- all those differing affordable grinds from competing manufacturers and their quality was superb.
Keep old mopars alive.
