An OEM willing gold Mopar Nationals 69 Swinger 340 is well know, and the original owner says it was orange. I have only seen a TSB that shows 69 Plymouth 340's were painted turquoise, never seen any other TSB that shows and other color, though people say their early 69 340's were painted red and later one's orange. I would love to see documentation on BLUE engines and any other TSB's that show when 68 340 red engines were changed to turquoise (or whatever) and another TSB that shows that late 340's were painted orange! They have to be out there!?! I have personally seen a few 69 340 Swingers from original owners that had turquoise 340's, but have not personally seen any original owner 69 340 Darts that were painted any other color. Of course I know there were 20,000 Swingers and GTS's built, but no documentation.
