explain to me why a 289 or 302 can't do better than 11-12 MPG. Is it because
Fords are gas hogs? >>
Mark-
It is not that 289-302 Fords CAN'T do better than 11-12mpg, it is that the
example cited DOESN'T. Incorrect float levels, incorrectly adjusted secondary
actuation (whether mechanical or too light of a spring in a vacumn secondary),
incorrect timing, very steep rear end gears keeping the motor buzzing at
4000rpm+ at cruising speeds etc. will all contribute to poor mileage. The
challenge is optimizing the set up so that the motor performs efficiently, not
blaming Ford as a producer of "gas hogs". The first thing I would do is figure
out what the fuel/air ratio looks like. My 302 Tiger w/3.31 gears knocks off
20mpg at moderate cruising speeds and my '89 302 Mustang (EFI) used to get
25-26mpg at freeway speeds w/3.07 gears. Heck, our '97 Explorer 302 will get
16mpg towing my race car!
