I had a 5.8 ford c-6 4.10 gears. my buddy had the same truck with a 460, got exactly the same milage. With a 3spd we would get 6-8 in town, and 4-6 mpg on the freeway (empty or loaded, didn't matter).
My truck had a rev limited speed of around 76mph.
For myself, I have been seriously considering starting to look for a southern/western 94-98 F-350 standard cab 4x4 with 460/c6/4.10 in imaculate condition. This action would probably result in threats of divorce from my wife!
