Hi, i am interested in buying a 1984 bronco with the high output 351, does anyone know what mileage I could expect? If american, add 20 percent so it is canadian. Can be american, I can do that. New here, great site. See ya.

 

I had a 84 f150 (same thing) and it got 10 mpg no matter how hard I drove it, I could baby it, or keep my foot planted on the floor and it would not change. I rebuilt mine with a small cam and holley 600 cfm carb. They have a lot of power, I was beating mustangs with her. I also had 3.55:1 gears.
