Ok guys, i feel really dumb posting this question, but yeah, here it is: what is a 289 bored 30 over, what does that make it, like a 293 lol ? i have no clue how to even figure it, dang i feel dumb. Sorry
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.
