So, RR, it flows better than a late carb or TBI intake?

Got one on my free '71 donor truck.

When the 273 first came out the engineers were trying to get it to fit under a hood, maybe Valiant or Dart. They chose the single-plane because it was lower, believe it or not. They were quite proud of getting it to work as well as a dual-plane. This is from an article on the "new 273" published way back when.
