I want to know how much compression does a 305 come with. It is a 1979 engine with the dish pistons, stock heads, edelbrock performer intake, 750 holley vac. sec. My father gave me this car and I want to know how much it has, to see if I can use a certain cam in it. tongue.gif

just guessing, but probably not very much...like 8.5:1 or something.
