I was wondering, what's the most torque/power people have put a 7.5/7.625 stock rear behind (and lived to tell, of course)? How about when it's strengthened with a differential cover/girdle and solid pinion spacer instead of a crush sleeve? ...just trying to get an idea of how much people have successfully tortured the 7.5/7.625 rear-end with ...stock or with the common mods.

 

it's not near as much a question of how much power they make as how much power they transfer to the ground and how quickly it's done.
