Dart 340 twin hood scoops

The twin scoops while they didn't do anything were a distinguisher from the base model Dart it identified the performance model probably more marketing than anything along with the tail stripe go wing etc. That being said I always liked the 68 Hemi Dart Pro stock scoop. While I dont see any "ram air" effect from the Swinger twin scoops I do see where it is a fresh air source or maybe it flushes the engine bay of excessive heat. That would be the only gain I see from them.
