16 in town, and 18.5-20 on the highway, but it goes down if it's windy (also does if I have a brake problem - I had a return spring fail on my right front recently, and it caused the shoe to drag, which reduced the mileage pretty badly). I'm running a 283 bored out to .060 "-over with an SM 420 transmission, and a 3.08 rear end. Carburetor is a fully rebuilt Holley 4360 Economaster.
