I doubt you're going to anything that will improve it much. I had a 65 F100 with a 240 six that only got 10. My 69 Power Wagon W200 with 318 V8 gets 8 MPG and it's rarely been driven over 55MPH. It does, however, have 4.88 gears.
M5 85 Ford F250 4WD ext. cab with 6.9 diesel gets a pretty consistent 13 MPG.
Years ago, when I had several Dodge powered vehicles (what was I thinking?), I made a sincere attempt to better my mileage. One with the 69 Power Wagon I still have, and the other with a 73 Motorhome powered by a Dodge 318 HD V-8. A guy I worked with did the same with his F250 with 360 V8. We bought new cams from crane (marketed for low end torque and fuel mileage), headers, Eldebrock Performer intake manifolds (supposed to increase fuel efficiency), and upped the compression ratio a step in all three engines. When we got done with our projects, we got ready to do some testing. Results - NO gain at all - NONE. The Power Wagon got 8 over 30 years ago, and still does today. The motorhome got 6 MPG, before and after. That I sold in disgust. My friend's F250 got 9, before and after. At the time we did this, there were companies selling plans for the magic "Pogue" carburetor that was supposed to quadruple gas mileage and run on gas vapor. My friend tried to build one and almost blew himself up.
I've got an 82 1/2 4WD Chevy pickup with a 379 (6.2L) diesel that averages around 17 MPG but will get 24 MPG on a flat highway. That's the best I've ever had. I even jerked around with that trying to do better, turning down the fuel delivery - and all it did was make it start hard. But - the Chevy is geared very high and is not suited for any heavy work or towing.
