MPG experiment....1976 Dart Lite

The best I ever did was 29.5 with a 198 with everything stock in my Duster. Exhaust anifold was cracked and I had a split exhaust into dual turbo mufflers. 3:23's. Maybe my pipes are 1.75" Average highway was 25.5

Find a super 6 2bbl carb. Make sure it isn't one from a 318!! There is a difference.

I am doing research on HHO systems. A friend was running one on his '06 Cummins and pick up 2.5 mpg grossing 22,000lbs pulling a trailer.
