Well if you're restoring the truck to be a perfectly restored show truck, I'd worry about the color, but if this isnt a concern, feel free to spray any color of HI-Temp engine enamle on it, like Plasti-Kote, and make it your truck! A few custom things will make it stand out from the crowd and make put a little peice of you in it that shows. I know youve put blood sweat and tears into it, and these dont show, except maybe the blood, but if thats showing, I think you might need medical attention

I have found pictures of these engines in Corvettes, and they were Chevrolet Orange, so they might have followed suit in the trucks.
