Nothing wrong with the 5.3, just dont expect that kind of power out of it with any form of reliability. You might get that power out of it once maybe twice before it destroys itself, if youre lucky.

I probably have 100+ 1000hp 4wd launches on drag radials with my 5000lb truck and the 250,000 mile stock transfer case looks brand new. Like I said, just dont shift it under power and it will be the last thing to break.
FWIW, the halfton tcase has a max torque rating of 1800ft/lb I think while the 3/4 ton tcase is 2100ft/lb.

If you look at the back of it you will see a round metal plate on the left side. It has the model number stamped on there.
The manual shift half ton case is an NP 261, the 2500 case is a NP 263. There are a couple others depending on if they are autotrack or electronic shift non-autotrack. Its easiest just to look.
But then I think GM changed the supplier from NP to something else on the gmt900+ platforms.
