Dennis: The engine will run with the cam one tooth retarded, but it doesn't have any power that way. Yes, the FA-65 cam will fit in the FA-72 but again, a major power loss if the 65 is the early one. If you want to try it, switch the entire cam box assembly, that way you wont have four tappets to worry about mixing up. Then you can, if you put the 72 cam in the 65, shock everyone with the really hot FA-65. Bill.
