Now that I have my sweet @$$ tune in my truck from Allen, I was wondering what pulley's would be the best to get. Also where would be the best place to get them at on line? I have heard some talk before the putting them on could cause some problems also. Is this at all true? Thanks for the help guys.

Electric fans, Headers, and possibly some NOS
I have my ASM pulleys on for over a year. They wanted to make sure to change both. The alt. will not turn fast enought to keep it charged if not changed also. My voltage goes down when at lights but a little gas and the guage goes back up. I heard it will help free up some howerpower.

I've never heard of that before? I've always just changed the crank pulley and everything else has been fine.
