Most Delco alternators that I am familiar with have separate fans, the fan is just pinched between the pulley and bearing spacer. The only problem that I have heard is that with the larger pulley the alternator wont charge at low engine rpm. Okay for a drag racer but not very good for a street driven car.

I have a small collection of alternators, and had one where the pulley & fan were integrated into one piece. But typically yes the pulley & fan were separate.
