72 Duster twister with the 275 horse 340 engine?

ie 69 roadrunner, black car with blue int. yes documented by all the buildsheet and tags. just an example.
and mopar was very eager to make the customer happy ( back then). a car could be ordered that wasn't available.. the example of the black road chicken with the bleu int. ( as yes it didn't not look pretty, to me.)

Black with a blue int was a readily available color combination for a RR in 1969
