Stock converter stall? 1600-1800 4.3 / 4L60e

Bought a 97 TJ set up with 4.3 gm with 4L60e tranny, dana 20 twin stick with a Behemoth crawl box (black box).
I bought it with a known weak tranny (slipping in 1st and rev).
I have a newly rebuilt tranny coming, but curious on torque converter stall speed.
From what I've read, it's probably better to just go with stock speed 1600-1800 with my set up to keep heat down etc.
35" rubber. Crawl ratio of 84:1 with crawl box (2.72), Dana 20 (2.46), 4.10 gears and 4L60e at 3.06 in 1st.
Any need for a beefier than stock converter? Was planning on the parts store $160 converter....

Thx gentlemen.

BTW, i did do a search but not much on here with my set up.

i know the 4.3L convertor stall speed is about 300 rpm higher than the same trans behind a v8.
i cant see needing more stall than that, unless it was hi power v8, at the dunes, or mud drags.

Finally found some info. Looks like the Dacco B29DCNF is my TC. It's 1800 to 2000 rpm .
