Really not at all concerned with gas mileage, just gas prices, LOL. I can remember buying gas in high school for 18.9 cents per gallon for leaded regular. Premium leaded was 21.9 per gallon. My 71 4x4 on a good day gets maybe 11.0-11.5 per mile, empty, downhill with the wind, LOL. My 71 Chevelle maybe 15-16 if I leave my foot out of it. The 700R4 OD trans helps it some if I behave myself. The 57 with the 283 and 2x4s mounted on top, mileage is most assuredly not a concern! Sure does sound good tho when I drop down a gear and punch it. SMILES PER MILE over mpg.
