need help with my build card and options

Don't know if this is much help, but I would say that your Barracuda is a Formula S car since it has the 235HP 4BBL 273. In '67 this engine was only available in Formula S 'Cudas and Valiant Signet 2 door hardtops. At least that is all I've ever seen the Commando 273 in or read about in dealership literature.
