I got ~12.5-13mpg with about 90% freeway (70mph) last time I checked.
1986 1/2 ton 4x4 in 2wd, 350, 700r4, 3.73 gears.
That was with a carb that didn't want to accellerate off idle very well so you ended up juicing it pretty good to get it rolling. I think that might pick up a smidge now that the carb is behaving better.
But I think that 14mpg might be the best I could hope for.
