What rear gears and transmission does your vehicle have?
Here’s what come up with for needed CC volume assuming you want a 9.5 to 1 compression.
Your total cylinder CC volume at .030” over is 886.55 .
Your total CC volume at TDC that you need for that 9.5 compression is 104.3.
Knock 72 out of that leaves you with 32.3 CCs
Knock 9.4 CCs out of that for the average head gasket leaves you with 22.9 CCs.
Knock 5.079 CCs out of that for a .018” deck height leaves you with 17.82 CCs
17.82 is the dish size you will in your piston to have a 9.5 compression.
