Gents, trying to figure out what the cc’s are on this piston will help in determining the overall CR. Specs on the piston as follows:
Bore 4.155
Clearance .008
Piston Net Dia 4.147
Compression Height 1.230
Ring Size 1/16 1/16 3/16 ors
Dish depth .210
Valve Pockets Int 2.200Exh 1.750
Depths Int .350 Exh .310
Pin Dia .927
My cylinder heads are 58cc’s. Gaskets: 0.043
Trying to find compression of my motor.
Motor: 431w
