    Just got the new cam in mail. I set up everything nicely and got strong spark! When I did the final torque (40ft.lb). Then it had no spark. The same problem happen, the new cam got crack! As per your comment, in the past the flywheel was over toquered and created the mushroom. Could I machine the flywheel to reduce the interference of it and the cam?
