I rarely get on the highway, but i will do a 4hr highway cruise soon

Depends on other supporting mods. Cam turbo stall? But if you're looking for a fun around town I'd say 4.10. I'm running 3.73 on 285-50-20s

4.10s if your a reg cab, otherwise 4.30s, 4.56. but if your going to do all that performance stuff, you should really get a shorter tire.

go with 4.10's or numerically higher.
dont know your tire size but ill brake it down using my tire size 265/60/18 (30.52" tall) 4th gear od in a 4l60 is .70.
70 mph
3.73: 2000 rpm
4.10: 2200 rpm
4.56: 2450 rpm

im rocking the OE g80 w/3.73 and i get around 18-20 mpg highway but when the time comes ill be swapping to the 4.56's

just my .02

just read your tire size but to lazy to re-enter the data
