273 comando non Formula S?
In 1965 the Barracuda Formula S should show "31" under the letters "AB" on the second row of the fender tag indicating a 235 HP 273 CI (4 bbl) engine. It should also show a "2" under the letter "C" which designates the Formula S package. If the second row of the tag shows "30" under the letters "AB" it is a 180 HP 273 CI (2 bbl) engine. The Formula S designator under the letter "C" is only true for cars from the 1965 model year.
