question, G body 7.5 rear life
 

In a G body stocker weighing about 3200 with a 305 stocker package, running low 12's high 11's

Will the 7.5 gear give any service life?

50ft or 50 seconds which ever comes first! Spend the money once and put in a 12 bolt. Several manufactures offer a complete bolt in.

If you are making decent horsepower and the suspension is up to the job,the 7.5 won't hold up. I thought a Grand National 8.5 would do the trick ;that piece failed after a few seasons .The answer is to do it right the first time with a 12 bolt and pro gears.

Yes to all above. Had a Firebird. It ran 13.60 and boom oatmeal in the rear end housing

Axles and internal parts are all about the same money, save for the extra cost of pro gears. Put the best unit in it that you can from the beginning.

Oldsmobile had a bolt in 12 for the G-boy racers. There are a few around if you know where to look.

I give up ... Where do you look?

News to me. Any more details?

Re: question, G body 7.5 rear life
 

None of the factory issued Oldsmobile Stock Eliminator cars had 12-Bolts in the cars. They all had 8.5 rear ends. Later on, a few switched to aftermarket 12-Bolt rear ends.

Find a 8.5 from a Grand National or 1984 to 1987 Olds 442 or an aftermarket 12-Bolt.
