Block color for 68 Slant 6

Mopar Folks!!!!! I have choices for the engine block color for this 71 Dart Slant 6 motor that will be going in my 68 Valiant. Which color should i paint the block?

Mopar red, Blue, or Orange? The block right now is Blue. But I can always change it. I plan on doing the Oil pan, timing chain cover, exhaust with ceramic silver paint. The valve cover will be chrome. All brackets will be flat black. The harmonic is sprayed silver as well.



Give me some ideas. Open to suggestions.
