Cam Degree Wheel

After properly setting TDC, the degree wheel allows you to check the installed intake centerline which may vary some. My first race solid was off by 2*. I adjusted from there. The degree wheel also allows you to verify the opening and closing points shown on the cam card on both intake and exhaust. With that confirmed any future changes in the cam timing will be known. It takes time to do all of that, but then you know what you have.
