Racah did you misread that mate? I read your reply and immediately got the idea that you must have read Mike's reply as "did it cause the stock belt to seize?"
Mike I'm pretty sure it uses the stock belt, I've got one on the other car. If Racah has been using it without any issues he probably has one of the new ones. Even so, if you do happen to buy it, before you put it on the block, bolt it up to the OEM pulley and make sure both timing marks line up properly. ATI made a batch of pulleys with the incorrect timing marks a while back. I was tearing my hair out for almost a year trying to figure out why my brand new stroker ran like sh*t before Brian mentioned the issue with the timing marks in another post. We remarked the pulley and bingo rock sold idle!
