You need to talk to a serious engine builder and I think there are a few on this list. A 600hp 383sbc pump gas n/a is no run of the mill engine. You need serious cylinder heads, valvetrain, induction and a bottom end to withstand serious RPM. I am guessing 6800-7200 power peak (maybe more) and capable of turning 7500-7800?? Don't get totally hung up on flow numbers, you need the entire combo, but head flow will be important.
Talk to a pro....Don't try a piece this thing together using a Jegs or Summit Catalog or any other catalog for that matter. Have a nice long discussion with a pro, answer the questions, know your budget, know your tolerance levels. Know that the custom built carb for this engine will be about a $1000. Know that a stock t56 won't last long with sticky tires at the track. Know that the fuel system for this motor could be pretty expensive $1000? A solid roller valvetrain will be $1000 at least....
Have you ever seen or driven or been in a car that has an honest 600 hp N/A motor? A small block? Not a 540 inch BBC, Not 450hp crate 383, not 500 hp 406, but 600 hp 383...not on spray.....not with boost, not at 13 to 1 compression, but good old fashioned crack the throttle and let her rip 600 hp on pump gas? I haven't, but would love to go for a ride in one....
600hp at the crank in a 3200lb car is a mid 10 second ride......at least
There is a sign on the wall in a friends shop and it reads something to this effect:
Pick any two of the following three things:
1. Fast Car
2. Cheap Price
3. Good Work
Because
A fast car with good work don't come cheap.
A fast car at a cheap price won't stay together long
A car with good work and cheap price isn't fast.
Do your homework.....
