I beleive atkins sells a set. But I would think twice about using underdrive pullies since they slow down your alternator and water pump. This can create issues with charging and cooling.

oh they do. well dose it make a noticable increase in h/p or are they not worth it. if not underdrive pullies than what kind

If you don't have an upgraded stereo or other electronic devices, I wouldn't worry about it.
supposedly you can see 8-12 HP with UD pulleys

well there is the problem. i do have an upgraded stereo. so now what do i have to do to keep those problems from happening.

Maybe if you get an FD alternator and rig it up to use the UD pullys that might provide enough power for it. Not sure though.
