Engine color 1969 Swinger 340

That motor looks more more like the "blue" than turquoise. Mopar turquoise is very greenish and not a bright/bold color, almost seems to have a hint of grey in it:

its turquoise. just 40 or so year old turquoise. time seems to change the color some..

I remember the turquoise
color but we called it Chrysler blue same as the 383s. It wasn't the same as the later blue.

thats because the later blue was blue and the earlier color that also came on the 383 was turquoise....lol
