What kind of mpg's can you expect from an auto SB A-body? The engine doesn't necessarily have to be built up. But something around stock. Is there any ways of improving it to get around high 20's on highway? Personally I drive about 60 mph on the freeway, but occasionally go 70 on longer trips. Very conservative driver. I know a member here had a 68 Barracuda trying to get 30 mpgs but he sold it for his new business.

318 2 barrel and 2.9ish gear driving the way you state should get you over the 20 mark, close to 25. Driven right they weren't all that bad for mileage and still had some steel around you. Not like the go karts they call cars now that should be getting a whole lot better in comparison and for what you pay.
