Mopar Gas saver?

Hey everyone!
Its been a while since ive had a chance to login but have recently developed a fascination with having an older A-body that gets decent gas mileage. Ive still got my 73 four door dart with the 360 and my 01 dodge 1500 that get terrible mileage. However, i have recently seen quite a lot of A-bodies on craigslist for very cheap and with the 6 cylinder auto setup. I was curioues if any of yal have any experience with these and what kind of MPG (town and city) yal got. Im looking at two different ones. One is a 74 swinger 2 door and the other is a 76 4 door. both with the 6 cylinder. I just finished a little plymouth laser I had redone and will be selling it soon. that being the case im itching for another little project! Any help (or recommendations on older mopars with decent mileage(, would be really appreciated. I am open to even older pickups and other body styles. But mainly want to keep the cost of the vehicle cheap up front if possible. Im just curious if this mopar gas saver is really just a pipe dream or not!
Thanks guys and have a good one!
JB
