Ron,

Here's the math:

Radius Squared x Pi = Area of a circle

Radius = Bore/2

Cylinder Radius Squared x Pi x Stroke x Number of Cylinders = Displacement

or

(Cylinder Bore/2) x (Cylinder Bore/2) x Pi x Stroke x Number of Cylinders = Displacement

Radius of a 4.030" (30/1000 over) cylinder is 1/2 of the bore = 4.030/2 = 2.015"

Radius Squared = 2.015 x 2.015 = 4.060

Pi = 3.14159

4.060 x 3.14159 x 3.70 x 8 = 377.5 cubic inches.

4.060 x 3.14159 x 3.75 x 8 = 382.6 cubic inches

4.060 x 3.14159 x 3.85 x 8 = 392.8 cubic inches

4.060 x 3.14159 x 4.00 x 8 = 408.1 cubic inches
