Slant Six mpg's?

I would gladly take some of your guys mileage.
Im only getting 7 mpg in town. Thats without idleing any. Easy on pedal to. Just replaced distributor cap and plugs. New air filter and fuel filter. I dont know whats wrong with it.
its a 73 swinger with 225 slant 6 automatic. All stock.

Well, rest assured that there's definitely something VERY wrong. Time to learn how to do some basic diagnostics (compression test, check timing and vacuum and read the plugs, for example), or take it to a mechanic to do it for you. My mildly hopped-up slant that runs rich STILL gets double your mileage in city driving. And I DON'T drive like grandma...
