I'm thinking about buying a set of underdrive pulleys for my 91' GT. First off, what are the best kind? Now the main reason for the post is after doing a search on here i saw people sometimes had trouble with their alternator when they installed underdrive pulleys. I have no idea what alternator i have on there, but i just had the vehicle fully inspected, so everything is fine. My question is.. will the underdrive pulleys cause any problems? Cause if they will then i'll think about skipping this. My upgrades are:
3.55's
flowmaster catback
shorty headers
catted h
ford racing valve covers
upgraded spark plugs/wires
aluminum radiator
bbk cold air intake
pro 5.0
tremec transmission
So, which u/d's and would they help? thanks a lot.
