No, the belt broke. I don’t think it was the RPM, I think it was the fact that the sometimes idiot car owner hasn’t replaced that belt since purchasing the car over 10 years ago..... it was a holdover from the original 383, who knows how old it was. I actually took the belt and ran to the closest auto parts store, matched up the length in hopes to keep rolling. But when I got back to the car, the new belt was way short, so it must have broke in two places and had a section missing.
