FYI: Stock Serpentine Pulley Diameters
Hows it going? I've searched all over this board for the diameters of the stock serpentine pulleys for reference purposes but found nothing so I thought I'd post them up:
Crank - 7 3/4"
Water Pump (long) - 6 1/2"
Power Steering - 6 1/2"
Alternator - 2 1/2"

Great Info. Any idea if I can get a shorter belt and reroute it when I delete my AC or do I need an AC delete pulley?

Re: FYI: Stock Serpentine Pulley Diameters
I've heard you can only reroute the serpentine belt when removing the smog pump (correct me if i'm wrong). As for the a/c delete, you're going to have to use the a/c delete pulley along with the shorter belt. hope this helps.

Re: FYI: Stock Serpentine Pulley Diameters
do you know how tall the stock tpi crank pulley is?
i was putting a paxton sc on my car and try to use a tbi crank pulley since i had underdrive pullies before, but its looks like the pulley needs to be like 1/4" taller so it can align with the rest of the accessorie's pulleys...
