hi, not sure exactly what info you're looking for, it's a 350 30 over, not sure exact compression ratio. vortec heads stk valve sizes, 2500 stall, i have both a 600 and 750 cfm holley carb, headers, 2 1/2 " exhaust, air gap intake, current cam 230, 480 lift, with this cam i was just going to add 1.6 roller rockers but i am thinking that while the heads and intake are off it would be a good time to change cam if that's what i wanted to do. not sure what else about the engine i can tell you.
