I have no problem getting the belt on, it is loose. The car had a 392 gatorback on it when I got it and I asked my parts guy to get me a gatorback for an 89 SC and that is the belt he gave me. I never told him I had a 392 on it already so I assumed 392 was stock length. I got a new belt cuz the other one was slipping at 3000+ rpm and wasn't looking so great either. The 392 fits on even with a bigger tensioner pulley that I swapped out with the accessory tensioner pulley and it is still maxed out?!?! I don't think the car has a OD pulley on the SC because it looks pretty old and rusted. Any idea what size the stock pulley is so I can measure it? The jackshaft also looks stock.
