A 305 with 2.73's and a Turbo 350, or a 305 with 3.08's and a 700R4 are good combos for getting really great gas mileage. Possibly into the 20MPG range. The 700R4 will be the best bet since it's got a lower first gear to make take off easier, and it's got the lockup clutch which will help out a lot too. I would go for the 305.
