The hood on my 70 Road Runner was called a Air Grabber. There was a switch under the dash that opened it and the air cleaner was sealed to the hood so as to give a ram air effect. Not sure how effective it was but it did give cool air to the carbs at the very least. The side of the air grabber hood had teeth on the side of it like the Warhawk airplanes of WW2. Seems kind of hokey today.
The six pack(Dodge) and the six barrel (Plymouth) were three two barrel carburetors on a high rise dual plane intake. The gas pedal was connected to the center carb and during normal driving it ran like a two barrel. When you stepped on the gas the two end carbs were vacuum operated. If they opened suddenly it would bog so the tipped in gradually. There were dashpots on the side of the two end carbs that you could change the guts and control how soon and fast those end carbs kicked in.
The center carb was pretty modest in size but the end carbs were huge, the total was 1350 cfm. It was probably a little over carbed on a 440 and a lot on a 340. If you looked at it from above and used your imagination the three two barrel carbs looked like a six pack of beer.
On my Road Runner I never got it set up perfect. It just never idled perfect. At full throttle it screamed. With that car and 4.10 gears, you really couldn‘t go full throttle in first gear. When you shifted into second you couldn’t stomp it, you had to roll into it or you would light the tires up. By third gear and fourth gear it was all out. With no over drive it was all over at 100 mph.
My car was manual steering with power drum brakes. The brakes looked like they belonged on a dump truck, big drums for a car. The 4 speed was what they called a hemi 4 speed, coarse ground gears for strength but it gave a lot of gear noise.
The car was noisy, and handful to drive, but when that six barrel was all the way open, it was a great sound. Sorry for the long post.
