Every manufacturing plant mixed their own engine paint. Slight variations but based on old paint on my block the closest match I found for mine was Ford engine paint in a rattle can. They use to make Chevy engine pain in a rattle can but is has been discontinued. Another interesting fact. I am not sure about previous years but in 54 if the engine was going into a truck it was grey. If it was going into a car it was blue. FYI - The oil filter in my picture is Chevy Blue and Chevy Orange.
