The cars were built by GM of Canada on the same assembly line as the Chevelles. They started out in 1962 as Acadian Beaumonts based on the Novas. When the Chevelles came out in 1964 the Nova based cars became Acadian Cansos or Invaders and the Chevelle based cars were Acadain Beaumonts. In 1966 the Acadian part of name was dropped from the Beaumonts but was still used on the Nova based cars until 1971. Not all SDs, Sport Deluxe, were big block cars. In 1966 and the first part of the 1967 production year the SD package was an appearance package and had small blocks as standard equipment. About half way through the 1967 production year it became a performance package with the 396 as standard equipment. There were no 396/375 hp Beaumonts built. There were less than 2000 big block Beaumonts built. There were only a little over 74,000 Beaumonts built from 1962 to 1969. It is generally accepted that about 10% to 15% of the Beaumonts are still around.
