Horsepower with mileage options

Start a new thread..."what are your build specs, mileage and performance"
..i'm betting there are small cam,14 " tire combinations out there that will get lots of rubber and 20 mpg!
I got the best of 20 mpg’s with a 4bbl equipped 360/904/2.76 gear with 235/60/15’s, in a ‘79 Dodge Magnum.
Working A/C, P/S, P/B, etc...
