sounds nice Tyler, should run very well, digging the cam, damn near the same as mine

what made you go dome piston? instead of maybe -2 or -3 fatttops with .052 mill ls9 gaskets ? was it cause the heads were already milled .040 ? just currious thats all, my compression is pretty damn close to yours at 11:9

[dirt track racer 81]

I was just wanting high 11 compression ratio. My heads were milled .030 and needed another .010 off when surfaced and had them checked and were 64cc chambers. I used the ls9 gaskets.

Heres how I figured mine. +cc you actually use a -. and wiseco pistons are 0 deck.
