Ok. So the formula would be pi are squared times stroke times number of cylinders.
The 396 bore was 4.096 inches, plus .060 inches would be 4.156 inches diameter.
Radius would be 2.078 inches (one half the diameter). Radius squared would be 4.318 inches (radius times radius).
Times pi (3.14159), that's 13.56 square inches.
Times the stroke (3.76 inches) that's 51 cubic inches. Times 8 cylinders, that's 408.05 cubic inches.

A 348 Chevy engine has a stock displacement of 348 cubic inches. When the engine is bored .060 inches over, the displacement increases due to the larger cylinder volume. This increase is approximately 5.1 cubic inches, bringing the total displacement to about 353.1 cubic inches. Therefore, a 348 Chevy bored .060 over is approximately 353.1 cubic inches.

There are approximately 460 cubic inches in a 289 that is bored 0.40 over. This can also depend greatly on what kind of weight the car is holding onto.
Boring a 396 engine 0.030 inches over increases its displacement by approximately 17.7 cubic inches.
