I have 4.8 with 4l60e in my 69. Currently 3.08 gears with 255/60/15. Freeway driving is great. In the foot hills where I drive is kinda lugs around. I find myself having to push more on the throttle to get out of over drive or I just down shift out of overdrive. I noticed after switching from billet wheels to the truck steel rallies this was more prominent. I do miss my billet wheels just base on the rolling mass difference.
