Small Block Stroker ... Gas mileage?

73Duster422,

I think 72challorange is right .... your foot is a big deal for this one.

The stroker in my 4speed Dart with 3.55s has a "life average" of 8.3mpg (there are ~1000 miles on it in ~20 months since the motor was done).....but the high is 13.5mpg doing 55mph pretty steady.

The cam is quite a bit hotter than what you are using which, combined with big ports, does not help MPG.

I think 20mpg with a light foot, in a light car, with reasonable gears can happen. GOOD LUCK!!!!!
