Very impressed with gas mileage

I’ve owned several A and B body Chryslers. All with small blocks. I just bought a superb condition, 2 owner 72 Scamp with a slant 6 with 60k original miles. I just returned from a 200 mile trip with that Scamp and averaged 28 miles per gallon !!!
My 11/1 367 did that with a [email protected] cam, all be it with a final drive of 3.55 x .71 x .78= 1.97 ................... and still managed 106 in the quarter.
Actually it did better than that.
If you had put this thread in the /6 forum, I wouldda not said anything, cuz I'm really not an azzole.. and Not a slanty hater.
