What will one of these things hold Tq wise... I don't think hp is a issue for breakage just TQ and since its behind a BB I'm curious what they will handle?
I cannot answer the questions, but traditionally they held up well. Problem with them was up-shifting @ high rpm. Personally, Ive seen hold up well in mid-low 10 sec cars that were 3400+ lbs.
Two companies come to mind that might be able to answer the question.

I have a brand new 833 od on the shelf...but if memory serves its slightly differant...and made for fitting into a gm pick up truck (gm used them for a few years)
