I put the BBK underdrive pulley set on my old weak AOD 87 GT that had 2.73s it couldn't even break the tires loose when hammering it from a stand still. Threw the BBK underdrives on and immeditialy noticed a difference I could actually break the tires loose when I hammered it from a stand still, I was very suprised how well they actually worked. So in my opinion underdrive pulleys r worth the money for how cheap they r.

they are a good buy if you dont plan on doing alot of major mods. if all your doing is simple bolt on stuff its worth the money. but the stuff you have to sacrafice for them isnt worth it down the road

I've got a set of black MAC underdrives that I installed as one of my first mods. The UD pullies probably made the biggest SOTP difference. I only installed the crank and water pump pully everything charges fine.

For some reason mine didnt charge very well at idle and the lights dimmed with the underdrive alternator pulley on my 3G alternator. Once I put the stock pulley from the 75 amp alternator back on the charging issues went away.

Most of the magazines and tech articles say that this is one of the best bang for your buck mods you can do. Definatly worth the price.
