Looking around the past couple days to help figure all the numbers for the motor and cam across these. Thought I would post them for other people future use.


Displacement = (Bore ÷ 2)2 x 3.14 x Stroke x 16.387

Head Gasket space = (Bore ÷ 2)2 x 3.14 x Gasket thickness x 16.387064

Deck Height space = (Bore ÷ 2)2 x 3.14 x Deck Height x 16.387064

Compressed Volume = Head Gasket space + Deck Height space + Piston Top volume + Combustion chamber volume

Uncompressed Volume = Compressed Volume + Displacement

Compression Ratio = Uncompressed volume ÷ Compressed volume


We dont need to stinkin SCR calculator to do it for us....
