How Do I figure Cubic Inch Displacement?

CU. Inch Formula

Cylinders x 0.7854 x Bore x Bore x Stroke = ------

Number of Cylinders  (8)

Multiplied by 0.7854....8 times 0.7854= 6.2832

6.2832 Multiplied by Bore 4.250 =26.7036

26.7036 Multiplied by Bore 4.250 = 113.4903

113.4903 Multiplied by Stroke 3.38 = 383.597

So it's a 383
