Wanting 500 hp (or close) out of a stock stroke 360

Aspen79 said
I'am try to get 500ish hp out of a 360 for my street car. The combo so far is
360 .030 over
10.5:1 compression
Eddy heads (pocket ported) (gasket matched)
Hughes cam .576/.588 .246/.250 @.050
Air gap intake (port match gaskets)
Roller rockers
Head and main studs
850 holley dp (way too big)

Again the goal is 500ish
Fully built 727 5 clutch pack, bolt in sprag and Cheetah full manual valvebody.

The won't be a everyday car. No long road trips, just Cruise around town, Saturday night street racing

The carb isn't necessarily too big, in fact, you'll need at least that big to hit 500, but you'll also need to port the heads to flow about 300 @ .600 and slightly more cam (duration). If you run 1.6 rockers with the cam you have, it will put your lift at .614/.627, so you might be close with that cam and 1.6 rockers and ported heads. When you port match the intake, go as far in as you can.

If you run it as-is, you'll probably be at about 420-430 at the crank. Port the heads, and you should be at about 500.
