    they will choke the engine, also they have small chambers so there hard to keep streetable. standard 350 dish pistions will net 10:1 with them.

    your motor is not set up for any comp ratio without knowing the cc of the combustion chambers. if the pistions are rated for 9.5:1 you need to know with what CC head they were rated with that, probably 64cc or 76cc, 9.5:1 at 76cc will be way to high with the 58cc heads, the 64's you would be pushing your luck. get whatever head the pistions get there 9.5 rating from

    chevyboi, I don't know if you're aware of this, but the camshaft must be matched to the static compression ratio. Find out all the numbers on the cam including the intake closing point at 0.050" tappet lift, the numbers on the pistons (so we can determine piston crown volume) and the deck height the motor was assembled at (how far each piston in down in the bore at top dead center) and get back to us. My best guess is that you have so much cam in the motor that it won't have any bottom end.
