 +  * Displacement: pi x (radius squared) x height (example: 4 inch bore, 4 inch stroke) = 3.14159 x (2 squared) x 4 = 50.265ci of displacement per cylinder 
 +  * Cubic Centimeters to Cubic Inches: cc ÷ (2.54 cubed) (example: 1200cc) = 1200 ÷ (2.54 cubed) = 73.23ci 
 +  * Cubic Inches to Cubic Centimeters: ci x (2.54 cubed) (example: 100ci) = 100 x (2.54 cubed) = 1638.7cc 
 +  * Horsepower: (torque x rpm) ÷ 5252 (example: 80 ft-lbs at 4000 rpm) = (80 x 4000) ÷ 5252 = 60.93hp 
 +  * Torque: (horsepower x 5252) / rpm (example: 100hp at 4000 rpm) = (100 x 5252) ÷ 4000 = 80 x 4000) / 5252 = 131 ft-lbs.
