3.42s are what my truck have. Cruise about 70 rpm are just about 2k. So highway not a problem, and I think its pretty quick. I'm close to 90 before going to 4th, been a while since I've done it, so not too sure.

Only one I know of is g80, and hear its trash, and pretty much a ticking bomb. Go tru-trac or something similar, with a gear kit. Maybe more but hey why go cheap. FI like you are, a g80 I would think would go pretty quick.

I'm running a 29" tire, with 3.42s, and it works out 3.54.
