When and why factory used dual snorkel?

360 FOUR BARREL DODGE RAMCHARGERS GOT THEM..
One long snorkel and a short one, did they help any, memike don't have a clue.

it should have been little red express trucks only not a ramcharger.

little red express trucks were the ONLY time a small block had a dual snorkel otherwise it's pretty much a big block thing because a dual snorkel allows more air to high performance applications.
