I can't imagine that the mileage on an 84-85 would vary too much from the fuel injected foxes. Just as a ball park, I would say to expect 22 or so on the hi-way and considerably less than that in town (depending on driving style, gears, etc.). If I am stictly in town, I probably only get 13 mpg or so. But, on the hi-way I can see 24 or so. Those numbers should at least get you in the ball park.
