The Boss Engine has been axed for future use in the Ford F-150 but the Super Duty will still be getting the engine as gas prices bypass the $4 gallon mark and the Super Duties current V-10 is less than stellar in the gas mileage department. The 6.2 ‘Boss’ Engine was also rumored to appear in a special edition Boss Mustang but that too has been axed, though some say it was never on the table to begin with.
