I'm a noob at figuring these things out what would be the new displacement of the engine if it was bored .30 over? Also what is the formula to figure this out?

357ci
CID = NOC x 0.7854 x Bore x Bore x Stroke.
8 x .7854 x 4.03 x 4.03 x 3.5 = 357
CID : Cubic Inch Displacement
NOC : Number of Cylinders

I have no clue. I guess some mathematician made it up. I just know it works lol.

The number 0.7854 is arrived at by dividing Pi by four (3.1416 Div. 4 = 0.7854)

i found that on site for measuring the gauge of a wire. maybe part of the equation for calculating the volume of a cylinder?

Yep! Now that you mention it I remember that from tech school years ago lol.
