I have that pulley on my Z28 and it works great I noticed that my car revs quicker, the only bad thing was trying to put it on

SLP, Powerbond, ASP and AFR all make UD pullies for our cars.

Do pullies add a noticable difference? Or any dyno proven results? Im trying to make as much power without having to throw a cam in.

I have one waiting to go on. I think it is one of the best out there because of superior dampening properties. SDPC has it for under $200.

make sure you have a friand when you do it and get the right tools getting the stock one off is no joy either.

i`ve done 2 sets now, imo they`re worth it but you won`t think so while your installing. also i had to use a belt a half inch shorter than mach tells you to you use but maybe it was just me

byunspeed has a specail that has the powerbond, 2 dayco belts and a bolt for 215 shipped. I'm probabally going to get that. I have ordered stuff from him before and he's pretty helpful and ships quick
