Can't beat the Edelbrock Performer street combo for best balance between economy/performance. You need EFI for ultimate best mileage but the performer is a good second choice. If you are serious about best mileage, get an O2 sensor and tune the carb based on air/fuel ratio.

Your going to want a wideband O2 setup to do any amount of decent tuning. Narrow band isn't accurate enough to do a good job from what I know.

Pretty hard to beat a well-tuned Quadrajet for gas mileage and decent power. Some people love them, some people hate them, but they will bring good mileage if you stay off the loud pedal.
