owned vehicles with the 223 inline six. My bro-in-law a '62 Country sedan and my brother a '72 F-100. Both drank gasoline like there was no tomorrow. CLLED "THE MILEAGE MAKER six" was definitely a misnomer, I think they were just too heavy a car/ytuck for the little six. Enough torque but just no enough hp. I drove both vehicles and pumpud a lot of gas in them.
