That is two times the bore diameter squared times pi times the stroke.

(2 x 4.00) x (2 x 4.00) x 3.14159 x 3 48 = 700 cu. in.

So a Corvette 350 engine is 700 cubic inches displacement? Shouldn't you multiply that by the number of cylinders?

Holy old thread batman...

as far as the gm 383 is concerned... they use a 3.8 stroke instead of the standard 3.75 to get around that ci difference.
