Post Rear End Swap Question

This might sound like a dumb question...BUT...I am building an S10 with a SBC(i know, i know)the truck was originally a 4cyl/5spd truck, 1989...What I am asking is this, how soon will I grenade the factory rear end with a mild built SBC? And is there anything that I should look for at the wrecking yard/swap meets for a good bolt-in Posi rear end? I guess what I am asking is what cars should I look for that would have a bolt-in rear end to fit an S10.
Thanks ,

You should be fine with the the stock unit.I have seen 400hp sbc in the s-series last along time.Stay away from slicks, they will cause the rear to grenade in short time.I also sent you a pm.

In 1989, the bigger 7.625" rear ends started to show up in some/most of the S-10 trucks. Prior to that, it was the 7.5". The housings are fairly similar, so I don't know how to tell you the difference.

BTW, all rear ends from the 1st gen. (and maybe 2nd gens) should be a bolt-in if you want to upgrade. The 4x4 used a 4" wider axle than the 2WD but spring perches should be in the same place.

I'm runnning a 7.5" in my 350/350 4x4 S-10, it's held up just fine. I'm not running gobs of power though it, though.

SLP used to sell posi units from the F-body conversions they do for $100, you could check them out. You need 3.23 or numerically higher gears to be able to use it. Or you could find a posi/disk brake F-body rear end and change the spring perches. I'm pretty sure they're wider, but you might be able to make up for this with different rims.
