Yea with a 5.72:1 first I would use the 3.55 without question.

I put a modified NV4500 in my 1994 K2500 Suburban which has a 5.61:1 first, the suburban came with 4.10 gears and first is way low. I will be swapping in 3.42 gears (tallest I can swap in factory diffs) when the project gets to that point.
