com on guys your telling me that this 460 won't get 18-20 miles to the gallon.... I am in shock lol ....sure does sound good and ride nice....maybe I could run it on moonshine, wonder what it would cost to make per gallon, to be honest if it gets 8-10 mpg I am ok with that, and if I get everything working maybe the wife will drive it in bad weather and leave the nice shiny power stroke at home
