On this site these cars will be considered G Body cars. “Technically” they are A Body cars, but not one part of these Grand Ams interchange with an A Body other than the Malibu which changed from A to G without changing much if any of the design.
These cars came with either a Pontiac 301 or the required Chevrolet 305 in California and in high altitude destinations. Yes, the 301 is a Pontiac as is the Beaumont, in my opinionĀ . Ok, maybe not the Beaumont…or is it?
