340 Dart paint questions

But why Blue? Unless your doing a concours resto. I bought a brand new 1970 340 4 speed duster and the engine was orange. IMO the Blue or turquoise belongs on C-bodies.

A 1970 340 would be orange, a 69 turquoise, a 68 red. That is just the way it was done. If you don't care about originality then paint it your preference...
