hey, I am installing a ported eaton with a 2.93 upper/ 4# lower and wanted to know what alternator pulley to get 3.2 or 3.? I know the 3.2 is listed as good for a 2# or 4# lower and the 3.5 is listed for a 6#, but alot of you are running and recommending 3.2 with a stock lower because the alt. is overspun from the factory, so wouldnt the 3.2 put it at factor speed (still overspun), I think I should buy a 3.5 but I dont want to spin it too slow, opinions please?
