I should be getting the fiberglass shroud next week from my 3.0 and I'm thinking of painting it orange to go with the Gulf blue on the body. Anybody have a better idea?

No, that is the best idea

If it's in plain fiberglass mesh without any gelcoat finish, you might want to leave it the natural finish - I think that is what the factory racers had and it looks good IMHO.

I think Red for the 3.0 S as they came from the factory or Orange to give the Gulf Race combo colors. Are you going to be using any orange on other parts of the car?

I thought I might add some orange pinstripping just as a highlight but I haven't fingired out where yet.

Orange on everything else. Engine shroud, rockers, bumpers, wheel insets, I think it is one of the best colour combos ever.

Agreed! Put Orange inside on the shroud and continue with the Orange theme.
Would look great!
