Think outside the box. As important as the color is how you do it and the materials. Once it's assembled clean really well with paint and wax remover or lacquer thinner. Mask and shoot it with an etching catalyzed primer, let it flash and coat with a catalyzed acrylic enamel or urethane single stage. Your motor can be any color you can dream of and the catalyzed paint will stand up to the heat and look great for years.In my 69 Dart I am painting the engine in a couple of weeks. I'll take plenty of pics so I can post here. This car is a blinding Seikens base orange in the engine compartment (body Color). My fear was the engine would get lost if I painted it orange so I have chosen a light charcoal metallic a couple of shades lighter than the alterKtion I installed. The M/T valve covers and the 6 pack lid are painted the matching orange. The intake and water pump are aluminum and will be left that way. The cost to do this your self is probably $200 in materials and you will have materials left over for other stuff. You will also need a touch up gun but for this type of paint work a cheapo works well. The results will be awesome and can not be matched for quality or durability with any spray bomb. It's a little more work but well worth it. Here's the valve cover and lid.
