1966 383 in my 71

Great, thank you for checking . at least I know that there are no Accessible markings that will give me that information.

Yes, even my 383 A body GTS doesn't have it, and the car is original. So Chrysler didn't do it on the 383. My 340 has a P on it after the 340, for some reason, as does the 273 and 318.
