I read the S10 swaping book by JTR. It says that the stock 7 1/2 rearend won't be able to hold up to big HP V8 motors. The book saysthe 7 5/8 rear will be able to handle the power. I plan on installing a 450hp+ small-block. Is there a way can convert my 7 1/2 to a 7 5/8 rearend? I looked at both rears and I can't tell the differance. They look identical to me. Also does anyone know of any company that sells Ford 9" rears to fit a S10?

Curry sells complete assy. also DTS. Probably cheaper to have one narrowed. Only cost me $1950 to get mine in.

just get an 8.5 from an s10 for it.

if you want to stick with the small rear though, which using an auto you may get away with it, just install a newer ring and pinion with a 3.42 gear and 28 spline axles with a detroit locker. a girdle may help also.

The 7 1/2 and the 7 5/8 are the SAME rear end. You could look into getting a 10bolt 8.5" outta a 4x4 dime or go for the 9"

Ummmmmm.....how bout gettin one from a 2wd insted. It just doesn't make sense to go with a wider one. In this case "wider is not better".

That would be ok, just throw some custom duallie fenders on with M/T's and use a zr2 axle, right?

Guys - Which years or models had the 8.5" rear? Specifically the 2WD. Thanks.

Yeah im lookin to, putting a 383 stroker in mine, i currently have a 7.5 with a zexel in it. I'm not looking to spend 2k though if there is a way around it.

i believe the 8.5 started in use somewhere around 94 or 95 in 2wd's. a well put together 7.625 will hold together under some pretty good power though. there are a few out there in the 10's and 11's.
