I'm putting a new piston in my motor, (440, stage 2 hotcam) and I was wondering if anyone knows, how high of a compression ratio i can run, without having to use race gas.

generally 11:1 is what most people will recommend for pump gas. anything higher, then you will probably have to at least mix in some race gas
