What is the best types of paints to use for my newly machined and built 401. I am going to do the block red, heads black, and leave the intake and aluminum accessories silver. I will be using some engine enamel for the painted parts, but I like the look of the intake and other accesories unpainted. From what I understand they will not stay nice looking for long. Can I just use so sort of clear coat or should I just paint them also? Let me know what has worked well for you.
