What to do with my 360

Heads are the best place to invest your money for power But saying that you said this is just a street engine and you already got ported J heads if there done right they should up there with most aftermarket heads and be able to support 450 + hp.

I agree with the others 360 has a pretty stout Bottom end, good pistons and rod bolts go along way.

I think your shooting for to much compression, on a street strip car especially if it see's a lot of strip time I can see pushing the CR but on 99% street car the extra 4-6% gain in hp ain't worth it. 9-9.5:1 will let you run most cams that you would want to use on the street anyways.

How much gear and stall are you willing to live with, will this car see a lot of miles, highway driving
?? Are things that need to be answered before picking the cam.

9.5:1 CR
Ported J heads
275 hydraulic roller
750
3.55
Would be my choices for a street driven 360
