Here is a list of
Chevrolet engine colors that has been around for a while.
Unfortunately, that list does not give color codes and there are many opinions about what is gray, blue gray, and blue. It would be very helpful if someone would post pictures of engines painted those three colors. There is one parts supplier that sells "gray" engine paint for trucks that looks blue (like the Blue Flame Six 235s that were put in automobiles after 1953).
