1976 plymouth feather duster and 1976 dodge dart lite

I would love you to check the ACTUAL GAS MILEAGE, I've seen folks claim 35 mpg, which I consider to be BS
i called the 2nd owner and he said 29 mpg, but the drum brakes are something to get used to.... and no power brakes, no power steering, no a/c, no hydraulic clutch, but it looks like it has a 340 or 360 with the hood on it......
