I am not trying to argue, but I do not believe any stock 8.75 can withstand 700 plus HP. Maybe 700 FLYWHEEL HP, but not 700 at the rear axle. Ain't happenin, IMO. At least not for very long.
Sorry to say but my buddy with the 750 flywheel HP blown 340 Demon has been running his with a 8 3/4 rear end for 13 years and no problems and that is with sticky street tires...he is not the easiest guy on the gas pedal.
