I have a 89 S10 that had a 4 cyl in it. I know the rearend is a 7.5 stock and weak. We put a 350 small block in it. And I was wondering what rear ends could be put in it without much trouble. From say a old Camaro or corvette. Or just a stronger one in general. Thank you.

 

Not sure about swaps from Camaro or Vette, but the S10 was pretty much the same from 1982 thru 1993. So any of those rear ends should almost bolt right in. You had two engines (4 & 6 cyl) then 2 and 4WD. That should provide you with several stock Ratios to choose from.
