will my stock 8-3/4" rear hold up to slicks behind my new motor? It will be a mild street 451 that should be in the 550 horse range once tuned properly. It's a footbrake / 727 car. The rear end has recently been rebuilt with all new bearings and a fresh sure-grip unit. But its an older gearset that makes noise and has stock axles, and it will be pushing a full weight 67 B-body.
