what do you have for piston in your motor? and what is your motor?   cause the heads that you got to put on it are open chamber. ( 882)

i have a 350 bored .30 over. dish pistons....and i did my math and now i know why my motor "pings" cause i need a higher octane fuel, what a suprise
it didnt start till i finally got a intake that actually fit over the intake runners. o'well, gotta do what you gotta do

you have dome pistons not dish piston?  dish is stock pistons.

[84silverado]

then i have stock pistons, cause mine are dish

[84silverado]

my math says i have 12.1 compression..my timing is stock

[betterbeaters]

get race fuel 110oct only if your that much comp.. and you time should be able to go up! lol
