Fordgarage,

I hate to disagree with you but the index slot in the cam for the rotor if in a wrong position will effect proper timing. Using the timing pin to determine top dead center, adjusting cam to point to number 1 contact in body so points just start to open, with the B cam in question had to move forward (advanced) to point to # 1 contact in body. When I installed the other distributor with stock cam, not changing the timing, the rotor was pointing between #1 and #2 contact in body (advanced); adjusted cam and everything was OK.

I have been timing my A engines since 1962 and this was the first Cam I have ever had a problem with. I have used B cams before without any problems.
