Just wondering how much abuse a 7.5 (3.42)rear end will take. I was told it has a better carrier in it but i havent pulled the cover to see. So far the rear end has gone 1.6* sixty foots. Car should be running mid 11's soon so im guessing the 60's will be getting better.

You gotta think about just how small the components of that Auburn are in there.
It won't survive for long.
The Auburn is by far better than a stock limited slip.
Believe it or not, I had a lot of luck with a Powertrax in a stock open carrier in a 7.5" in a V8 S10 years ago.
They do click but that's just because it's a very positive engagement.
I never ran slicks, though.
The little wheelspin I had at launch probably kept it alive.

ya i have a felling that its going to break sometime this year once i get the new motor in. i have been doing some 1.6* 60 ft.s and i plan on get some 1.5's this year since i have done a few suspension changes. The reason i have a 7.5 in the car is because i bent the axles on my 8.5 and i was young and didnt know any better about the 8.5

Holy Cow! 1.5's and 1.6's on a 7.5?
What's your secret? Divine intervention? ha ha ha
Please post the carnage pics when it finally gives up.
I'd build your old 8.5 in a heartbeat.
They're popular, parts are readily available and it's a no-brainer bolt-in.
Rather than starting from square one with a 9" or something.
Unless money is no object for you.
the rear end got swaped out about 8 years ago and the car sat for a long time. right now im doing 1.6* sixty foots on 100% stock suspension with old tired out shocks. im going to be looking for a new rear end im sure before no time. i know who to turn to as soon as this one lets up.
