Common Formulas for Stroker engines

image41


•Displacement in cubic inches = Bore x Bore x Stroke x Number of Cylinders x .7854 

•Assembly Height = (Stroke / 2) + Rod Length + Piston compression height

 •Rod Ratio = Rod Length / Stroke

 •Mean Piston Speed (feet per second) = (2 x Stroke x RPM / 60) / 12
