I have DOZENS of pictures of original 69 A-Body's taken by yours truly that include plenty of original owner cars and they ALL had turquoise engines. The anomalies have just recently (within the last 5 years) come out of the woodwork with different color engines. I personally had a two owner 69 Dart GT convertible that was a late build with a 273 engine that was blue, no doubt about it but that car was crushed 10 years ago. With the factory TSB's I have and have seen that show turquoise was the 69 340 engine color, I tend to believe those. The one I show above has a date code AFTER the August 1st introduction of the 69 model year, so other 340 engine colors could have happened before Chrysler made the change, and maybe there are some examples of orange painted 340's before the end of the model year.
