OK, how many of you guys can remember the gas shortage of the 1970's? I drive like an old man most of the time as I learned how to drive with my Dad telling me there's an egg between my foot and the gas pedal... don't break it! The blue car with a fresh 455 4bbl, TH400 and 2.56 gears got high teens on the highway all the time. One trip with four adults in the car and the trunk full of luggage three tanks averaged 21 mpg on regular gas in the 1980's. Later I took that engine out to put in a 1970 442 and installed a 350 4bbl that had been recently rebuilt. Same trannie and rear end got 17-18 mpg on the highway. My job at that time had me traveling throughout Oregon and Washington State so in one summer I put 30,000 miles on the car and that's the consistant milage I got. No idea on city driving, but on the highway with normal driving the 350 and 455 got about the same milage.
