What was this hood scoop on?

That scoop appears to be from a 1972 Demon 340 or a 1973-74 Dart Sport 340/360 car, it sould have 2 part numbers on it, one on the lower part that screws on, the other on the scoop....sweet score!

It actually looks like a 72 Demon scoop with the flat bottom at the front, 1-year only scoop!!
