max compression on pump gas\steel cylinder head\241 @ 50 cam
running a 360 +.030 with 915 "j"s cc at 59, the static is about 11.3, pistons are the speed pro h116cp's i think??? flat top with 5cc valve notch at zero deck. .039 gasket, cam is the comp 520/540 lift with 244/252 at .050 duration 110 lsa, intake closes at 67 ABDC, cyl psi is 205 to 210, i run 93 about 18 initial and 30 to 32 total, have to do all the tricks to keep it happy, but i love the instant start and idle, and great low end torque.
