I don't keep track as I'm not a Pro drag racer or bracket guy but more than some slower cars who kill their 8 3/4's in short order and again, who cares and all good on my end cos I KNOW what I have and I've tested 100+ carbs on my car and drive it like at the track to properly verify afr's and power but must say, my motors tired and time for a freshening............

I don't want to sound like a jerk but if you have a car that can run in the 9's and use a transbrake at a track and the car hooks up, a 8 3/4" rear end will brake.

I'll even through out a number, whithin 15-20 launches.

Foot driving will keep them alive, Brett Miller is proof of that.

Totally agree and probably my saving grace as well as Bret and other FAST azz cars and a 9" will be the rear of choice when the time comes to step up............ thumbs

Oh man that's ruff. Bummer your stuff went 'clunk'. Hope the fix is quick and good in time for your next run. That dana looked like an old hockey player missing all those teeth.

The worst beating happens in the first foot or two. I would have to think a very efficient converter behind a high torque bigblock is the toughest on the ring and pinion, if you don't use a brake and it hooks hard.

I might be wrong but looking at the ring gear, it looks like trans locked up first and that broke the ring gear.

I've been running my 8 3/4 with a alum center
for years.. the car is light.. leave the line
at 5600 rpm shift at 8200.. I broke a totally
stock one when a cap broke(thats when I changed
to the alum center.. weight is the killer
EDIT
every launch running a trans brake

8 3/4 have their places.. let's face it if you're making a fair amount of power in a heavy car it won't last very long on a decent track..💣

Posts like this could go on forever and are a waste of time. Some cars sit in the garage for years without hitting the tracks so unless you have some numbers on passes, et’s, weight, etc etc etc it’s “fake news”.
