That ratio surprises me - my father in law had a '79 Chevy 2500 with a 350. If I recall, the final ratio and with a granny geared trans was in the 4.50 range and his mileage was horrible - like what you are getting. But by then in his life he only drove it 2 miles for coffee or 15 miles to my house to help me on my additions so it really didn't matter.
