Help me figure out my compression ration...tried calculators!
I already tried the c-speedracing compression ratio calculator and input my numbers but they dont make sense. This is my set up...
-81.5mm wiseco flat-top- according to the catalog the are -4cc and 9.7-10.2:1 ratio for b18c block and 9.3-9.8:1 for a b18b.
-b18c5 block
-ls crank
-b16 head milled .012
The calculator does not have a place to input numbers on the head (milling).
When I input -4cc in the piston displacement section I get ~9.5:1
If i input 0cc because its flat top I get 10.2.
Any help would be appreciated.
