I have 3.08 in my 10 bolt. Perhaps some day I'll get to try her out. I also have a 3.73 gear set sitting by and have been coached to swap because of the better pickup. I am more interested in cruising at 70 mph/2000 rpm.
Short story, I don't know what is best. 3.42 might be just right, depends on what you are looking for.
