Need Advice on Rear End

[MJS73]

I currently have an open 2.76 8.75" rear end in my car and I'm looking for advice on how to upgrade.  I'd like to end up with a 3.23 limited slip and would probably lean toward aftermarket as opposed to buying an old 8.75, although that's not cast in stone.  Any thoughts?

If you're state side Dr. Diff has good pricing on total axle ass'ys, or you can get just the diff from him I believe in the area of $1050 US . Strange Engineering and Randy's  were more $$  the last i checked. I put an Auburn diff with 3:55 gears in my Cuda/340/4 gear.......works well so far........dk

for similar cost you could build a Dana 60

I'll check those out, thanks.  As for the trans, I have a 904 and will probably swap it for a SB 727, or is there a later model 4-speed auto I should consider?

518 is the 727 based 4 spd with OD there are some threads here on how to install one

Thanks, I think the Gear Vendors 727 with OD is the way I'm going to go.

it will mess with the exhaust system fit but otherwise I have not heard anything bad about the GV unit

If I just want to keep the rear end simple and go to a 3.55 posi (and I understand that the 741 case is the "weakest" of the 8-3/4s), do I need anything other than this?

If your going to drop the money why not do this?

I wouldn't go with a 741 housing. For that price you can get a 489 or 742.

Take your time (if you can) and look around....I found a whole 3rd member at a swap meet (741, 3.23, posi, clutch style) for $175.00...I just took the posi out of it and slapped it in my 489 case with 3.91's.  Total cost was around $600; that includes the 3rd member, richmond 3.91 gears, seals, bearings, etc.

   all day long now....

A few companies sell complete rear units for that much and less.  Check out manciniracing.com or the parts for sale board here and at moparts.com.  I'd be concerned as the picture in teh auction doesn't show a pinion yoke installed.
