Now, I stripped all the chrome from the Parts Pack Cadillac 354. Looking online, seems to be its a bored-out 331. I've found engines in green, blue, dark blue, black, and silver. What color should it be? It's going in a hot rod, and I may paint it CAT Yellow to be different, but I'd like a definitive answer on color in case I decide it fits with the style of the build.
