Power limit of a 12 bolt?
Have a reubild 12 bolt rear everything except the housing is new. New Eaton 3 series posi, Richmond 3.73 gears, Tom´s KA 30 splines c-clips axles and offcourse new bearings. How much horsepower will it hold up for? Know that I should have changed the ends to Ford style ends. Have another 12 bolt laying around to build up later. The car is a 3400 heavy chevelle 64 with aut. and 2500 in stall. The engine will be a 489 with at least 500 hp, not planing on slicks with this rear but who knows?
