I had a co-worker who wanted to regear early 2000's GMC 2500 with a TBI 350. Had stock 3.55, and he put 33" tires on it. He had a small toy hauler trailer. He was thinking 4.10, I told him with the 33" tires and hills where we live he should go 4.56 to keep the 350 in it's power curve. He went 4.1, told me after his first tow he wish he had listened and gone 4.56.
If you decide to sell and get something more recent, get a 6spd. The 6spd pretty much makes the axle ratio a non-factor.
I'd bet this was a late 80 to mid 90 motor if it is a tbi. The vortec went from about 95-2000 or so, then that motor ie 5.7/350 was discontinued about then in favor of the 5.3.

Maybe it wasn't tbi, I am a lot more familiar with Ford :) I just remember it was about the last of the GMC badged GMT400, had the 5.7, and he was not happy pulling the grapevine with 33s and 4.10.
