Value of the car

The Duster I own is all original. Original motor, wheels, paint, car jack even.

I just got it and i love the idea of the "classic" muscle car look like the little wings they had em on cant remember the wings name, and the hood sccops, hood pins with the matte black accents. The problem is I like the idea that it's all original and I'm able to say that.

If I added a hood scoop, wing, hood pins, and the matte black typical paint scheme how bad would it hurt the value of the car or my ability to say it's all original and it been seen as so.

Sorry if this doesn't make sense or if it's a dumb question, i appreciate any and all feedback guys, thanks!
