With this formula, you can determine the compression height of your pistons. a = Block Length (centerline of crankshaft to deck surface) b = Stroke of Engine c = Rod Length d = Deck Clearance Formula: a - (b / 2 + c) - d Example: 9.025 - (3.50 / 2 + 6.00) - .025 = 1.250... (more)
This formula will give you the dome volume, in CCs, needed to reach your target compression ratio. a = Head Chamber Volume (cc) b = Gasket Volume (cc) c = Deck to Piston Volume (cc) d = Cylinder Displacement e = Target Compression Ratio Formula: (a + b + c - (d / (e - 1.00))) x -1 Example:...
