14 MPG would be the upper end of my guesstimate.....probably closer to 12.
A 351M isn't the most fuel efficient beastie Ford ever built.

yep this, and if its in a 1 ton expect closer to 6 all the time. They are terrible on gas, have no power, but there dependable. We have a 81 1 ton that was bought new, and its still going.

I'll say, I had a 400 in an 83 F150, basically the 351's big brother. Did a great job moving that truck, would pass anything but a gas station. Didn't like too many R's though. Much past 4500, kiss the bottom end goodbye.
