It was first offered on a 72 demon. Never on a Duster. The direct connection chassis manual recommends this scoop and the T/A challenger scoop as the best scoop for induction on a Bracket car. That is why you see them being used on different cars.y cars back in the day had these scoops installed. Ford's , Chevy,s and other Mopars for a cool forced induction intake charge. It was on the big end where it would start to work but only if it was sealed to the air horn on the carb. Sort of like a low boost at high speed. QUOTE
Back in the late 70's Tom Hoover (father of the hemi) had a 69 'cuda notch that was originally a factory 440 car. He converted it to a W2 headed smallblock and was a 12 second car in street trim. It was blue and had the Dart version of this scoop. It says a lot that he picked this scoop. The Ramchargers/Direct Connection engineers did their homework on this one.
There were 2 versions, one was profiled on the bottom to fit the ribbed Duster hood and the other fit the peaked hood 73-76 Darts. The Dart version also fits the beaked 69 Barracuda hood. I've seen both.
I too see them on non-Mopar cars and trucks and it looks weird to me.
