Fuel Mileage on your Hemi swap?

With the cost of gas nowadays, I was curious what kind of fuel mileage people are getting out of their hemi swapped A body cars? If you have any mpg data on your setup please share! (vehicle, 5.7, 6.1, 6.4, stock/modified, transmission, rear gear, etc)

See, I would like to have my Barracuda be my daily driver since I can literally drive year round here in AZ. I'm thinking a stock '09+ 5.7 with an OD trans should get me much better mileage than my current daily Dakota (16city/20hwy) and yet still be a blast to drive.
