interesting Mopar trivia, I've never heard of until now, in a Hagerty article

In 1969, both the Road Runner and Super Bee came standard with the 335 horsepower 383. It was painted orange. 

The non-performance 383 4-barrel was rated at 330 horsepower and was painted turquoise. 

The main difference between the two engines was the camshaft. 

However, if you ordered a Road Runner or Super Bee with air conditioning, Chrysler installed the milder 383, meaning AC-equipped Road Runners and Super Bees received the turquoise 383.

 Chrysler handled this dynamic differently in 1968 and 1970
