I don't know about the other guys, But I ran the B2600 2WD rear end which is a direct swap, I put the RX-7 FD torsen LSD in it and I was making 390whp on 9psi with a vortech S-trim on my 5.0 and had 265/30/19 tires - it would go sideways in 4th if I wanted to.
I now have the exact same diff setup in my turbo 2200 and it works great too.
I ran that same diff for 6 years with the 5.0 and some of that was daily driving to the tune of about 70K km, that truck is still running today and the diff is fine, I think you'd be fine with a stock 26002WD rear end, the B2200 rear is VERY weak, I have seen them broken with the stock motor and the speeder gets are tiny. Keep in mind that burning out on an pen diff just murders it because now you are transmitting 100% through the spider gears and that is bad...
