So im building an engine and im having a hard time accepting the answers i get from these calculators people made different answers everywhere.
I made my own and it gives me a very different result.
This diagram should explain what im trying to do. Compression ratio = total volume divided be compressed volume

Engine specs are:
bore: 4.125 inches
Stroke: 3.4
Head gasket diameter/thickness: 4.155/0.030
Piston to wall gap:0.006
Height of piston to first ring: 1.090
Deck clearance:0.008
Dish in piston:22cc
Combustion chamber volume:58cc

My calculation got me 9.88:1
Hope you guys can help me verify this!
