It will smoke the tires, it will get up and go. This converter will probably be good when I get my cam. I can sit at a light and let my foot off the brake and the truck barely moves if it moves at all.
what does it take to put the TB TC in an 01 tahoe 4l60e

Yeah, i think it's a simple, direct swap if I skimmed through the thread correctly. The "hard" part is just doing the actual work.

Of course, you could also just call someone like Circle D or similar and give them all of your specifics like vehicle, weight, cam, gear ratio, etc., and get a torque converter ordered or custom made.

Note if it wasn't mentioned: make sure you check torque converter to flex plate spacing, 1/8" to 3/16" (obviously, also make sure converter is seated properly into the transmission pump), and make adjustments if necessary.

Just buy a converter for your setup. The 4.2L TB converter is barely better than stock.
getting a quality 3000 stall will make a huge difference in performance for the same amount of labor.

I went from 2.2 to 1.88 60' times with a trailblazer converter. Not a bad gain for the budget minded. especially if you grab one from a junk yard.
