same piston as me...except im .040, does that mean it is like a 357 also?

yes itd be the same because i am .040 over and that equals up to 1 mm, so 357cc

Take a look at powroll's site, they have the simple equation there. You just convert the bore and stroke to cm, and afterwards do the following: bore x bore x stroke x constant.
