Underdrive pulleys........
There was a post quite some time ago on this subject and I can't find it. Where is a good place to find some inexpensive underdrive pulleys? Working on a '93 with 5.0 Thanks

I ran across a site that basically just sold pully sets. The only drawback to underpully sets is the effect on alternator output and the problems that can bring. They carried sets for "daily driver" vehicles that supposedly work around that problem. If you want I'll try to find it again.

Umm... not always. The BBK Underdrive Pulley sets allow you to reuse the stock belt and still gain 8-15 HP.
This is only an issue if you have a bunch of electrical accessories. The the average driver any set of underdrive pulleys will be just fine with little to no effect on charging or cooling.
Again, BBK pulleys are great for this reason. Stock belt is used with little or no effect on accessories while still gaining 8-15 HP...
