Agreed. For the amount of time it took the OP to post this he could have googled it, entered the values and had his answer.

wideopen231I always used 1/2 bore squared x 3.14 x stroke x # of cyl.Thewn nobody use same formula for compression as I do.
Curtis just figured do math for you. You get answer, teach you math and you will always have answer

183NThe formula for volume of a cylinder is: V=pi*r^2*h where r is half the bore and h is the stroke. Then multiply by 8 cylinders.
