1973 Dart Swinger Gas mileage

Not bad. I get that to about 19 with my 70 Swinger. Not too much you can do that will make a huge difference or cost a lot of money.

Thanks had a 1973 back in 1973 same car basically only I put a 4 barrel of a 340 on it and a set of headers thought I was getting better mileage but maybe not this one is stock.
