318 build #2 "cost minded" for the '74 Duster

Yeah club cab with 5.2 is in the 15's in the 1/4.

Maybe you already mentioned it and I overlooked it, have you run the 1/4 and done mileage testing with the combo that is in the Duster now?
Ran the 1/4, went high 14's but not with the dual quads, it was with the singe 4bbl. I've not checked mpg.
