Question

I need to know what engine size do i have.Chevy small block 350 board over by 60?

Answer 1

Or stated another way without a slide rule...

Bore x Bore x stroke x .7854 x Number of cylinders= Cu.in

4.06 x 4.06 x 3.48 x.7854 x 8 = 360.422

Answer 2

360.42 cid, to be exact.

The standard bore and stroke is 4.00 x 3.48.

new is 4.06 x 3.48

The radius is 2.03, so now it's just math

The area of a circle is pi times r squared which is 12.946, times that by the stroke, you'll get 45.05, times that by 8, you'll get 360, rounded off
