67 Dart, stock 5.7 with TTIs and ModMan intake running Megasquirt 2x injection, 4 speed (non O/D), 8 3/4 rear with 3.55s and I believe ~26" tall tires has got me around 16 mpg. It weighs a little under 3400 pounds as I recall from the last time I drove it across the scales at work. Working on a T56 swap now, so hoping to up that to more like 18-20.
