What cubic inch displacement would this be???

Alright I have a 440 magnum im gonna bore .30 over, and thinking about a 4.15 stroke,what would I end up with? Also I am looking at staying at 10.5.1 compression how would I achieve this? I am using eddy performer heads a Mopower purple cam .509 lift and flat top pistons speed pro or srp,eddy performer rpm manifold, This is all just depending on what $$ allows. thanks alot!!

standard bore 4.32"+.030 over = 4.35
4.35x4.35= 18.9225 (bore squared) X 4.15 (stroke) X 8 (number of cylinders) X .7854 = 493.4

(one of many ways to determine CID)

displacement?

My engine has 4.372 bore-4.15 stroke=498cu inch

Thanks alot guys I thaught It was a 493 but couldnt remember the math for sure I think I am looking at building a stroker engine.
