Yours wasn't/isn't Unorthodox though was it? (not saying that in a rude way just from what i remember it wasn't)The Unorthodox pulley is the only pulley I would ever put on my cars. All the others are junk and should be thrown away. There are many post on the others causing catastrophic engine failure.

Well thanks, thats good to know, i still have a chance at the sale now. LOL
Does that mean Your interested? LOL
willing to take offers on it, hit me!
I just copied and pasted it from the website here is what they say:
Power Gains:
Unorthodox Racing pulleys can provide gains of 5 to 12 HP and 4 to 8 ft.-lbs. on normally aspirated engines and 8 to 16 HP and 18 ft.-lbs. on forced induction engines. These are average gains. Gains as high as 37 HP and 45 ft.-lbs. have been realized on modified forced induction engines. These gains are obtained in two ways.
First, and most important, is the weight lose. An average of 2.7 HP is gained from every pound lost off the crank shaft. 85% of the gains are from weight loss. The rest of the gains are from underdriving which accounts for about 15% of the total gains. These pulleys do not push underdriving for two main reasons. The first is to keep charging systems, air conditioning, power steering, and water pumps moving fast enough for everyday driving. Second, not much horsepower is gained from extreme underdriving. All of the underdriving is done with the crank pulley, not the accessory pulleys. This is done so maximum weight lose can be achieved at the crank where most of the horsepower gains are found.
