I use a different formula. I don't get pi involved. LOL I use the old school bore x bore x stroke x .785 x number of cylinders. Works everytime. ALL you need to figure cubes is bore and stroke. PERIOD. The 456.3 is correct for the info you gave.

This is correct and the easiest formula to use. To the OP.....your posts are INCREDIBLY hard to read and understand!
