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

Another question: Do I need to get a different size belt??

big cube 426

yes

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...

Hi , im new here, hope im doing the post right, You have to be carful w/ underdrive pulleys if u using them on ur every day truck. like some people said here , u may have problems w/ alternator amd water pump. but all deppend where u live and how hot and cold gets during summer and winter.If it gets hotter than 100 F during summer and ur driving on city. u may over heat the engine. hope everything works for u.

on my 95 i had to get a 2" short belt and my alternator doesnt put out as much "Juice" when sitting at a stoplight, but i have not had any over heated problems.... i took my clutch fan off and put a dual electric fan on and my truck runs cooler with the stock thrmostat
