    1. Love these cars and the fact that there is a web site dedicated to them. I did find a couple of the stats for the 73-77 Grand Prix are different than I’ve seen elsewhere:
      1) the 73-77 Grand Prix and the Monte Carlo were built on what G.M. called the G body platform. It was basically a slightly larger 2 door coupe built on a 4 door frame.
      2) both the Pontiac 350 and 400 2 barrel engines were discontinued after the 1976 model year
      3) in 1976, the base engine was a 350 2 barrel.
      4) in 1977 the base engine was a 301 2 barrel
      5) all Grand Prixs equipped with a Pontiac built engine from the 301 2 barrel to the 455 4 barrel were equipped with the THM 400. The only Grand Prixs of this generation that were equipped with the THM 350 were the ones sold in California and high altitude locations in 1977 that were equipped with the Olds 403, Olds 350 or the Chevy 350.

    2. Thanks for the note. It all makes sense, so I made the changes.

      Some of the powertrain offerings listed were straight out of books I have. In hindsight, not all ‘official’ options on the factory list (that book authors use) make it into production for a particular year.

      As for the A-body Special nomenclature, I’ve seen that exact term used on GM documents of the era, but I understand that they’ve also been called G-bodies over the years, so I added the secondary note above. As far as I know, the ‘A-body Special’ term was only used in the Colonnade era, with the ’72 down being called G-bodies from the get-go.
