Alrighty. Im trying to figure some things out. But I cant seem to find some solid spec numbers to even get a correct stock compression ratio with a calculator. Does anybody know what the specs are??


Cylinder Bore Size 4.00
Piston Stroke Length 3.62
Head Gasket Bore Diameter 4.135
Compressed Head Gasket Thickness .052
Combustion Chamber Volume In CCs 71.06
Piston Dome Volume In CCs Negative For Dished Pistons (Use '-') -8
Piston Deck Clearance Negative If ABOVE Deck (Use '-') .006

Are these numbers right???????????

 

Stock gasket bore is 4.04"

The rest are very close.
