I had basically the same engine in... a '94 Corvette. I had a huge range in mileage depending on how I drove it: 10-29mpg. If I was being good, it wasn't hard to stay in the 25-29 range though. Mine was a manual.
Besides the tranny, the big differences are:
- Weight. Maybe you can try to remove some mass.
- Aerodynamics. Some of the aero tricks may help here, but that fact is, it's a big car.
- Gearing. 0.5:1 overdrive in the manual... But the auto was still geared higher than your car with 2.73:1 differentials. It may be worth switching over.
Switching to a manual shift probably won't help enough to matter. The big problem with the auto is the inefficiency of the tranny design. You need to use power to operate the pump and you'll always have the torque converter to deal with.
