Cam for a 360 build with the parts i have

you didn't say whether solid or hydraulic lifter.
if Hyd, maybe something about [email protected], much more than that and you will lose low end and probably not gain much on the top end because hyd lifters aren't going to be happy past 6k rpm unless you have everything setup perfect.

the tough thing at the moment will be finding something in stock if you are looking to buy quickly.

this has good info, a smoother street hyd cam vs a faster solid cam.

there is another dyno test that had edelbrock heads which might be more inline with what you could do depending on how well the RHS heads are prepped. I will try to find it and post it...
