Try bore x bore x .7854 x stroke x # of cylinders

2 x 3.1415 x 3.898 x 3.898 x 3.622 = 345.779446882504
2 x 3.1415 x 3.905 x 3.905 x 4 = 383.2384963
2 x 3.1415 x 4.00 x 4.00 x 3.622 = 364.112416
2 x 3.1415 x 4.030 x 4.030 x 4.00 = 408.1662988
It works for V8s at least and that's what he asked for. Try it for yourself if you don't believe me.
