Default 454 with .060 over pistons, how many cubes?

I am buiding my 454 motor with .060 over bore, how do calculate extra cubes? What size will it be, 470? Thanks for the info!

I believe it is either a 467 or a 468 (I'm building one right now). A good Internet site with lots of caculators, including a cubic inch calculator, is http://www.smokemup.com . :cheers:

Correct me if I am wrong but a 454 is 4.25" bore x 4.00" stroke.

.060 over means the bore becomes 4.25 + .06 = 4.31"

Displacent = displacement per cylinder x 8

displacement per cylinder = area x height = 3.14 x (4.31/2) x (4.31/2) x 4.00 = 58.33
(area = pi x radius x radius)
(height = stroke)

58.33 x 8 = 467 (approximately)

467 cubic inches

If you really get down it 466.9 is the correct number, but most just call them 468's.
