do you know your deck height?
Clearance Volume = Piston Deck Volume at TDC + Piston Dish Volume + Head Gasket Volume + Combustion Chamber Volume
Swept Volume = pi x Bore^2 /4 x Stroke
Compression Ratio = (Swept Volume + Clearance Volume) / Clearance Volume
Clearance Volume = Piston Deck Volume at TDC + Piston Dish Volume + Head Gasket Volume + Combustion Chamber Volume
Swept Volume = pi x Bore^2 /4 x Stroke
Compression Ratio = (Swept Volume + Clearance Volume) / Clearance Volume
