cubic inches

The 350 that i have in my car is bored .30 over and I was wandering what the formula is to figure out what that changed my cubic inches too. So does anybody out there know how to do this?

You have 355 cubes.

Pi x (Bore/2)squared x stroke x number of cylinders

3.14 x (4.03/2)squared x 3.48 x 8

3.14 X 4.06 x 3.48 x 8 = 355.

I know you wanna figure out the cubic inches, but if you want to find out the cubic centimeter's (Litres when you move the decimal place over three), just multiply your bore and stroke before the calculations by 2.54
