What I don't know and would like to find out for myself is can you swap the FC alternator pulley over to an FD alternator without any machine shop work? FC's are v-belt, FDs have serpentine belt pulleys. I *think* the FD alt has a larger diameter shaft, which would mean the FC pulley would need to be bored out to fit.

Most use a pulley designed for the FD alternator to be used in FC applications. It properly spaces belt grooves to align with the water pump and crank pulley.
I got mine from japan2la, a forum member on 7club that made pulleys specifically for this application, and even made them in many colors. I am not sure he is around any more. Occasionally they pop up used.
