Anyway, you could mod the 5.4L with an intake , headers , flow thru's and a nice cat back system - that alone would catch it up in mileage with a stock 4six..

I'm not joking about the mileage though. She gets over 20 on almost every tank. It gets 20 when we all load up and go on vacation.

Did you remove her silencer too???
Kidding aside - I managed close enough to 20 to call it 20 mpg once - Think it came out to 19.8 something. That was on cruise 65mph thru flat Ohio on the turnpike ..
Once I hit the mountains in PA - forget it!! That was just to much fun
