Ford made the good ol' 240 and 300 inline sixes starting in 1964, and they had the torque and longevity to be great truck engines. By 1983, however, pushrod sixes were going the way of the vinyl LP- quick, get a metric designation on that thing, so buyers will think it's one of those newfangled V6s! We're a little skeptical that a Late Malaise F series pickup ever got 30 MPG highway, but maybe that test was done at a "highway speed" of 42 MPH, using a liquid measurement known as "Ford Truck Gallons," which are equal to 1.5 regular gallons.
