If you are building a car with all the latest things (cooling fans, AC, sound system, and power everything), you need to upgrade to a more modern alternator.
I appreciate this info... Most of these alternators you mentioned run a serpentine belt. Unless the pulleys are interchangable, I prefer to stay with the V belt drive than change out all the pulleys.
