Those are one of the few "fake scoop" designs that I love...probably because of my ridiculous bias to love anything to do with a '67 GTX. :D
The '66-'67 Plymouth Belvedere/Satellite body is a very formal, clean, chiseled looking shape. Those scoops (along with a few other slick GTX specific styling elements) are just so subtle and understated...yet they do the job of conveying that there's a monster under the hood without showing off or being tacky.
The '66 Hemi Belvederes, wicked performance cars by every measure, were total plain jane looking sleepers. Some probably prefer that. To me, they're just a bit too serious in the styling department.
