???? On flycuting and compresion
Also trying to find the flycutting thread I thought it was a a stick ,if it is can someone steer me in the right direction .
Quick instruction. Put the piston .500 down. Calculate bore x bore x .500 x .7854 x 16.387= cc of a flat top piston. Now measure your cc's with the piston in the same spot. Subtract the smaller number from the bigger number and thats your valve relief volume in cc's.
