**edit** I just realized I can't spell "if" worth a damn in the title! I took some pics of the blower pulley and the snout bolts. Can any of you tell me if you suspect the pulley to have been changed at some point? I see what appears to be rub marks behind the pulley. Perhaps a really small pulley rubbing at one point? Also, it looks as if the snout bolts have been touched. Why would this be? Perhaps a ported blower? With what I am fairly certain to be a stock car, I'm seeing app. 8-9lbs. of boost. I wouldn't think it's ported. Any commentary is appreciated.
