Re: Taking '70 on a road trip - should I swap trannys?

Actually, I already did that. I was running 265/75R16s and I found a set of 265/85R16s off an 80s 4x4. It helps a little bit, but it's still screaming at 70 MPH.

By the way, for those of you who have stock 3/4 tons with the 4:10 rear end, how fast do you go on the interstate? How fast will these trucks go?

Thanks!
