What engine compartment color do you think?
If you plan to drive on the street regularly and plan to paint the outside of the car a light color paint under the hood black.
You will likely get a lot of guff about it being a Chevy thing but a good idea is a good idea where it is Chevy or not. A light body color under the hood gets grimmy real fast and it pretty much impossible to keep looking good. A satin black finish will not show the grim and will look better longer.
I painted my engine compartment body color and after the first few thousand miles I have regretted not following my own advice. The next time I have an occasion to pull the engine it will be black.
Also, regarding the outside color. Don't listen to anyone and paint it the color that turns YOU on.
