I know there are a few on here that have the underdrive pullies so I will let them comment on the quality of the brands that they have. I too will be looking to get pulleys at some point and did some reading up on them. I have read good things about both the March and the Jet pullies for the 4.3L.

 

What kind of power increase can you really expect from those?

 

Not really an increase, but free up some power. 2-5hp typically. It just turns all of the belt driven accessories slower. So your wp, ps, and alt will all turn slower than stock. I didn't mention the a/c because at WOT, the a/c clutch is disabled.

 

Yes and you want to be careful with pullies if you have an audio system that draws a lot of power. Even with the smaller alternator pulley some people still complain about having charging problems.l
