  • 74 firebird production no:s for formula 455's only

    hi, does anyone know how many 74 firebird formula 455's were made ? i know the total of all formulas from 74 exceeded 14000 but cant find any info on production of diffrent engine sizes.

    Which 455? Auto or manual? One of my books shows 731 firebirds exlcuding trans ams were sold with the X code 455 with automatic trans. And 212 firebirds excluding trans ams were sold with the X code 455 manual trans. The X code is the SD 455 and the Y code is the regular 455.

      Well I read a little futher and those numbers are for Trans AMs. There were 58 total formulas with the 455 SD.

        The only 455's that were 4 speed were SD's in 1974, all other 455 cars, T/A's and Formys, were autos otherwise.

          That's incorrect. My numbers above show the actual numbers for 1974 SDs

            And all the rest of the info I have for 1974 is that outta the 14,000 Formulas most had the 400 but there was a Y code 455 option.

              The Y code was for 455's like you said, but only the X code SD's were available with a 455/ 4 speed combo. The Y code cars were all automatics.
