so 915 with .040 quench what compression can I run and still use pump regular or premium?




About 9.5:1 with the steel heads.

I dang sure dont agree with this statement. Im running 10.5 with open chamber iron heads, without any detonation problems. No quench whatsoever. Of course I have a decent sized cam, 259@.050, but 9.5 is on the conservative side.
