Here goes a formula for you.
CID = NUMBER OF CYLINDERS x SWEPT VOLUME

Which makes CID = N x 0.7854 x bore x bore x stroke (all in inches)

You would have 8 cylinders x 0.7854 x 4.030 (4 inch bore stock plus another 0.030) x 4.030 (have to multiply it twice) x 2.87 (stroke)

So, 8 x 0.7854 x 4.030 x 4.030 x 2.87 = 292.86 cu. inches... Good guess on the 293.

My 289 is bored 60 over, so it's a 297.
