Engine Cubic Inches = Bore (in.) X Bore (in.) X Stroke (in.) X number of Cylinders X .7854
Engine Cubic Liters = Bore (mm) X Bore (mm) X Stroke (mm) X Number of Cylinders X .7854
Find the Stroke When The Bore And Cubic Inches Is Known:
Cubic Inches or Liters ÷ Bore ÷ Bore ÷ .7854 ÷ # of Cylinders
Example: Chevy 350
350 ÷ 4.000 = 87.5 ÷ 4.000 = 21.875 ÷ .7854 = 27.852 ÷ 8 = 3.482
Find the Bore When The Stroke And Cubic Inches is Known:
Cubic Inches or Liters ÷ Stroke ÷ .7854 ÷ # of Cylinders then find Square Root of This Answer
Example: Chevy 350
350 ÷ 3.480 = 100.575 ÷ .7854 = 128.056 ÷ 8 = 16.007
