BIG blocks and 8 3/4 dont go, lol

First question is how much power and torque was being use on the car.2)if you are using over 500hp and torque,and think you can run stock caps at a drag strip,its your own damm fault.3)After market caps are CHEAP insurrance to failures like this.4)Who set up the gears? There is nothing wrong with having a 8.75 diff behind a BIG BLOCK or hemi and making it last,did it for years and never a problem.This is more of a set problem than a cap failure,mrmopartech
