Special For JPlante:
I am a member of a tightly knit community of classic coaches.
They were all delivered with a 3.07 final drive (rear end). They were all delivered with either a 455 or 403 engine. Their weight in use varies between 9500 and ~12000#. We all get between 8 and 10 MPG almost without exception.
Those that do better are those that have changed out the final drive to higher numerical. Those are available at 3.42, 3.55 and 3.70. Owner that regularly logs the best fuel rate has a 403 and 3.70.
Just to add to the data field, there are more than a few that now have 500cuin engines and some of those are port fuel. Few that have 8.2 mills, do about the same but man are they quick. The very few diesel conversions only do about 15.
The amount of alcohol in the fuel makes the most difference. Mileage decreases in almost exact proportion to the amount in the fuel.
