/6 Mileage ?
My '69 valiant 4 door gets 24 mpg. highway at the speed limit. It's a '75 225 auto stock with 2.76 gears, holley 1 bbl, electronic ignition, and a good tune up. I've had quite a few /6 cars and trucks over the years, and that's typical i've found. Nothing is good on gas if you put your foot in it! The best I've seen is a '82 Miser 225/6 4 spd od. truck that got 30 at highway speeds that we went on a long trip with. I drive my valiant 800-900 miles a month! Subtract 15% for U.S. coversion! They are a good, reliable engine combo if you don't beat on them and take them for what they are,I bet the dart lite would get 30 mpg. U.S. if driven right.
