Steeda U/D Pulleys????

I am thinking about buying me steeda U/D Pulleys.

I was wondering if this is a good buy or not, I can get a pair for 160.00 brand new.

My current mods include: 70mm TB, C&L Intake Plenum, Granatelli Motorsport Pro M90 MAF, 75-125 Shot of nitrous, mac off road H Pipe, and race mufflers.

Thanks for any help in advance.

Good addition, but don't expect miracles. The U/D pulleys on a 4.6L don't work near as well as they did on the old 5.0L. You may rev out a little easier on your way up the power band, but I doubt you'll see much more than a couple of horsepower.
 
Same stock belt. I do rev up easier . I feels like I did gain some more power. Not tons of power, just enough to notice. BBK claims 10 to 15 HP. Probably more like 8 to 12.
