I had a 68 ford f100 with a 240 inline 6 ( under bored 300) single barrel carb, three on the tree (no overdrive), and 3.50 rear end gears. I got 17 mpg driving the hell out of it so I would think a 240 with a 4sp with overdrive could possibly get 20. Not to mention my 240 felt like it could push over a house and also had enough power to spin the tires.
