1966 Dart 225 Slant/3 spd power/MPG?

If you change over to a super six 2 bbl intake & carb rather than the 1 bbl you will see improved milage between 22 and 24 mpg or better and responce will improve too. Mine did in a "snap" like that, I suspect the 2bbl handles air and fuel better than the 1 bbl. If you drive like you did with the 1bbl you should see the 21/22 mpg, watch your foot do the speed limit and you'll see the 23/24 mpg. Plus the hard starting on cold mornings improves, won't go away but improves. That helps the battery . Oh! yea, the motor will still be stock.
