What's MY engine's Displacement?
We can use this Calculator with this formula to calculate the displacement: Enter what is Blue. (that in parentheses appears on its screen)
1st: Press (enter) "C" to clear the computer.
Then enter 3.175 (std. Bore) + 0.030 (oversize) = (3.2175 new bore) ÷ 2 = (1.6085 is 1/2 the bore) x 1.6085 (times itself) x 3.1416 (Pi)
x 3.75 (stroke) x 8 (number of cylinders) = 243.88 cubic inches displacement.
If you know the bore & stroke you can skip the first part: 3.4375 ÷ 2 = 1.71875 X 1.71875 X 3.1416 X 4.125 X = 306.26 (the biggest!)
