In 1969 you could get a 340, 383 or even a 440 with 'Cuda Package it was not just a M Code thing. You had to check off a Special " A56, A57 or A13 Code " on the order slip which was clearly marked "'Cuda Package" View attachment 1715346466
Just a question in the middle of this knowledge competition,
You buy a 1970 car - you can order it in and pick it up in 1969.
Same with a 1969 vehicle, able to order and pick up a 1969 vehicle as early as 1968. Correct?
