75/76 Dodge Dart /6 average MPG and improvements

If it's high MPG you want, the '75-'76 slants are not the best candidates. I bought a '75 Valiant Brougham brand new, and it was the only A-body that I really disliked. I traded a '68 Fury 318 that got 14-15 city and 18-22 on trips, for the plush, but woefully underpowered Valiant that averaged 12 and 15 mpg.

On the other hand, my son bought a very high mileage '69 Swinger 225 auto and used it to commute to his job at a ski lodge 40 miles each way. He got low twenties and usually carried one or two other workers on the commute. Mixed driving in summer averaged near 20. It had nearly 300k when he sold it, and the only major repair was a $100 transmission rebuild from a friend.
