What's decent? I used to get 16-17 mpg at 70 mph with my 068 cammed 400 with the TH400 and 2.56 gears, and 14 mpg at 85 mph with an 041 cam, 3.23, and 4 speed. I always was of the opinion that Pontiacs gave pretty good mileage, as my buddies with their TA's regularly knocked down the same mileage under similar conditions.
