As you can see this is a regular question with many different answers. My problem is that I suspect that most if not all of the answers are correct. Now to Svenn's question concerning a C15A there is photographic evidence from period photos that the Chevy engines were painted gray. Accept all three of my trucks `41, `42 and `43 with apparently original engines were painted black.
Cheers Phil
