Why can't a 3.9 be made to get some better mpg?
It's a 318 - 2 cylinders. Is it timing,cam,injection,gearing, or all of the above? I was thinking about taking a pre magnum. Adapt a small
carb to the throttle body manifold. Talk to acam grinder about grinding a cam. And use a standard ignition. In a short box Dakota with a 5 speed, Why couldn't it get upper 20's. Feather Dusters have been known to do better than that with a /6.
