Truck engines didn't change for a couple more years as I recall and I also have seen '78 Vettes with factory engines that were Orange so they must have held out a little longer as well. Maybe becuase the trucks and Vettes didn't get "corporate engines". On some models back then you didn't know what the heck it was going to have under the hood, Chevy, Olds, Pontiac or Buick. Quite a few B-O-P new car buyers tried to sue GM for fraud when they found out their new Buick, Olds or Pontiac had a Chevy engine under the hood.
