9.3 compresssion
edelbrock performer rpm manifold

flowmaster exhaust
comp cam xe274
specs

thanks

I come up with 372 ft. lbs @ 4000 RPMs
373 HP @ 6000 RPMs
Personally I think a 625 Road Demon would be perfect for this combo

379 lb-ft @ 4500, 382HP at 6000 for a 600 carb
379 lb-ft @ 4500, 384HP at 6000 for a 625 carb
382 lb-ft @ 4500, 391HP at 6500 for a 750 carb

but all this is on a perfectly tuned motor. If you ever get it dyno'd, let us know what the numbers are.

is this a good combination?

looks pretty good

how much would 1.5 roller rockers add?

hard to say, DD2000 assumes a perfect world, so Id assume thats with roller rockers.

1.5 rockers are standard size. roller i dont think you would even get a full hp out of them alone. to make the most of roller rockers you should build a full roller motor.

thanks
