250 six for fuel efficient project
Interested in building a light weight, fuel efficient 73-79 F100. Have the opportunity to pick up a solid running 250 sixer. Is this a good option for this project?

The truck will be basic transportation. I will be reducing weight and attempting to get it to around 25 MPG. I have no experience with Ford sixes aside from the 300. This engine is in a Maverick and is essentially free, other wise I wouldn't be interested.

As I said it can be made to work. But the difference in fuel economy of a 250 and a 240 will be small versus the difficulty in cobbling in the 250 with trans linkage, radiator, transmission mounts, throttle linkage, motor mounts and miriad little other things makes the 240 a better choice. With a little parts counter help everything is available from Ford to bolt in the 240.
Your biggest MPG gains will come from chassis prep: tire sizes, gear ratios, aerodynamic aids, stuff like that that has been discussed elsewhere ad nausium.
As a teenager I once had a chance to get a Falcon convert and a free 272 Y-block. I made plans to swap in that dynosaur of a motor. I thank God it never came to pass.
Sometimes free isn't cheap enough to be practical.
