3.23 great all around gear and wont rev the crap out of your engine.

Sounds like 3.23 is the way to go. Now I just have to find one. If I was doing mostly freeway cruising, would you still recommend the 3.23?

How of big of a job is it to swap out the 4.1 for the 3.23, if I can't find anything else?
