Stay in the 3's, thicker. Get a TA diff Girdle but as most will tell you our diff's are on borrowed time some have luck and lots don't. My experience I've had 5 camaros and 2 gave me problems on close to stock power just mild bolt ons. The other 3 with nitrous and full bolt ons and I was lucky no issues running 4.10's. When it breaks it is costly because in my case I had to replace more then just a ring and pinion. Either way goodluck.

Your best, cheapest and strongest 10 bolt will be a used one from a junkyard from an m6 car with 3.42s. It'll cost easily $600 to put new gears in, over $1000 if a shop does it, and you can find a used 10 bolt with no damage (be sure to pull the cover and inspect it) for $200-250. I'm on my 3rd one, 1st one was fine but I sold it when I bought the 9", second one i was an idiot and didnt inspect and had chipped teeth, 3rd one I inspected and is fine again. Hunt the classifieds long enough and Craigslist and you can find a 9" or 12 bolt for $1200-1500.

OP go 4.10's if you aren't planning on launching on slicks or racing the car a lot, get a girdle anyway for insurance. 4.10's are the only way to go for a 6spd, they actually make 6th gear much more useable...

Had a set of Richmond 4.10 gears mikronited quite a few years back, ran them on the stock differential with girdle and the stud kit for the bearing caps.
Somehow the damn pinion nut came loose, chipped a ring tooth. Who knows how long it would have went if not for that weird fluke? I destroyed it in proper fashion, at the track.
The deals are out there, I paid $1250 for a Moser 12 bolt, with an Eaton posi inside, 4.11 gears, axles big enough to beat a giant to death with, AND it came with a Denny's Nitrous Ready driveshaft.

Theres some austrailian made 7.75 inch rear ends for third gen camaros ('87-'89) with a nine bolt cover that should fit. They are mostly 3.73 geared as i understand it. I dont think u even need a brake conversion but u should do your own research. I believe these were a G92 option for the Z28 and maybe the transam also on B2L cars (350" TPI). I think they put these in late model GTO's also but not in the same housing.
But remember this rear end is marginaly larger than our 7.625" rear ends and will be only marginaly stronger. I dont expect it to be as strong as even a Dana 44 as it is a smaller diameter ring gear. Just a cheap rear end with your 3.73 ratio as no one wants them and they should bolt right up - but please do your own research.
Yea i though 'bout cryogentic treating some 7.625 gears for a swap to the later LS 4th gen rear swap when i found out the 7.625 gears have the same part number as our 7.5 rear ends. Why bother swapping rears for the same size gear set? But i still want something a little stronger that bolts right up, fairly cheap, has low power loss, cheap to swap, nearly as light as the stock rear,. And did i say cheap?
Lets us know what u find as it helps us all.

The stockers will last if the bearings are kept in good order. A solid pinion spacer will help keep the pinion in place but will be more noisy. Any of the major brand gear set will work, but most of them have two sets for mild duty and for heavy duty with the heavy being more expensive. Yes Cryo-ing a set will make them stronger, but it is hard sometimes to find someone that will do them at a cheap price. So all in all get a good set and have them done by someone who knows what they are doing.
