Roughed into Pipemax. It all depends on how everything works together.

384.570 Cubic Inches @ 7200 RPM with 100.00 % Volumetric Efficiency PerCent

Required Intake Flow between 255.3 CFM and 269.8 CFM at 28 Inches
Required Exhaust Flow between 175.0 CFM and 197.4 CFM at 28 Inches

600 RPM/Sec Dyno Test Lowest Low Average Best
Peak HorsePower 554.4 577.2 588.6 600.0
Peak Torque Lbs-Ft 448.2 466.7 475.9 485.1

HorsePower per CID 1.442 1.501 1.530 1.560
Torque per Cubic Inch 1.166 1.213 1.237 1.261

BMEP in psi 175.8 183.0 186.6 190.2
Carb CFM at 1.5 in Hg. 801 891 936 982

Target EGT= 1264 degrees F at end of 4 second 600 RPM/Sec Dyno accel. test
Octane (R+M)/2 Method = 107.1 to 110.0 Octane required range
Air Standard Efficiency = 64.59206 % for 12.900:1 Compression Ratio

Peak HorsePower calculated from Cylinder Head Flow CFM only
600 RPM/Sec Dyno Test Lowest Average Best Potential
Head Flow Peak HP = 486.2 569.9 653.6

Looked like a pretty good build list until we got to the Edelbrock E-Street heads....you could have done a lot better there for the same price point. They'll be the cork once the intake isn't.

Holley Strip Dominator intake, #300-25 or better yet the Keith Dorton version #300-110
Probably the Professional Products Hurricane second choice, Super Vic third.

You're not going to get to 500 Hp with just a 185cc head.

Interesting you brought up the 300-25 Eric. I was going to suggest a worked over Super Vic first as I've had better luck with it than a Strip Dominator but with those E-Street's it would probably be a better match.

I would guess about 475 - 500 would be the max with that build
Granted I don't know much about those Edelbrock heads but I must be seriously over estimating them. My buddy built a low compression 9:1 383 with a set of old RHS iron heads and a much smaller cam and made 485 which I thought was a turd.

sounds like either lose some cam and compression and make a street motor or put some heads on it for a race motor...what are you using it for?

This engine is available locally from a fellow racer. $3800 freshened, intake to pan. Considering using it in a light footbrake chevyII. Th400 with 8" converter and 5.13's for 1\8th mile fun. Nothing serious, budget deal. Thanks for everyones input.

dump the heads, keep the intake if you must, buy a set of the cheap, shocker, cnc ported 225cc pro-max heads, buy them bare and build with a good set of Ferrea valves and PAC springs, You will have about $1600 in them when done, port match the vic jr and get a 2" spacer. You will have 600hp.

I don’t know, but we did 3, 355’s with world products Sportsman 2 heads, no porting allowed, that did 560, to 592 at 8,800. I just don’t know how they compare to those edelbrock heads.

I would think 500hp would be easy with this package. I made 500hp and 460lbft with unported, 3 angle valve job, 2.05int valve phase 2 bowtie heads 30 years ago. 355ci, 12-1 comp, .650 lift flat tappet cam, unported victor jr and a stock 650 carb/1" open spacer (all by rules). These heads were right around 170cc, and flowed less than the e-street.....?

Sorry. Wasn’t ignoring you. Just now seen it. It was for Wissota A Mod. My first try was with a stock block, stock crank, JE pistons, Carrillo rods, and a set of Sportsman 2 heads. Heads were not allowed to be ported at all. Edlebrock intake that was worked by Ron’s, Comp Cam made to peak at 8,500. Stud mounted rockers, pulled I think 562. We never ran the cheater heads, but we did get to 238 cfm flow with a 2.05 valve. Next 2 builds, again, stock blocks, gas ports, titanium valves, lite trick Callies crank, a cam change, and made 586 and 592. Angle milled the heads as much as possible. Some of the guys running the cheater heads were over 600 hp.

So i bought the long block in post #1.
Pretty stoked. Finally a decent engine. Going in an older tube chassis chevy II. 2500lbs me in it. T400. 8" tc. 5.13s. 1\8 mile duty.
Thinking some different heads like mentioned above? I will have some iron sportsmans available, heavier with more runner cc. More suggestions appreciated. Cheers!
