Probably only if it was a survivor. You'll probably need to pay big bucks for parts to do that and no way it will add up on final value. Now, to keep it original looking, yes. I tried to do that with my Duster. Not a valuable car, so by keeping it all stock looking, base, slant etc What was once everywhere, is now less common than every car having a high HP 8, hood scoops, stripes etc...
