my blue 71 beater gets 16+ mpg

[Ozark Tim]

I find myself with a new 72 beater every few years (it's a virus I think)
This year I bought a 71 Custom 10 with a 307 V8, 3-spd manual with optional 3:07 diff and only a few minor options. I guess the optional 3:07 diff really helps on the mileage.
I drove it to the farm 2 weeks ago and brought a different truck home and then brought it back this weekend.
I averaged 62-67 mph and got over 16 mpg on it. I have made the trip back and forth since 1975 so I know the miles and didnt do the wrong math. I guess I am used to my 11-12 mpg 350's.
