My cousin has a '71 Chevelle it's a bracket car, weighs 2920 with a 555 CI,runs 550s in the eighth mile with a 12 bolt. He was only getting about a hundred runs out of a ring and pinion but switched to a 488 I believe has a larger pinion? It has a t a girdle on it and good axles and spool but it's nothing special.
