Re: Bronco mileage.
my 86 EFI 302, with better exhaust and ignition and stock sized tires nails down 15-18 mpg (on an American gallon).
In the Summer I have touched 19.75mpg and once 22mpg on a long, low speed trip.
In the Winter it can drop dramatically depending on how cold it is, the knobbier tires, the tire pressure, whether I'm in 4WD,length of warm up, etc.
I'm a leadfoot off the lights and drive 70-75mph on the hwy, with 1/4 savage city traffic driving, 3/4 expressway/hwy cruising. When anyone else drives my truck it goes up 2 or more mpg.
I'd think a newer shortbox F-150 with a bed cover or no tailgate should out to a Bronco gallon for gallon.
