The grabber set up does look good under the hood though. All that duct work and the oval air cleaner.
The Snorkel and T/A scoop were the only scoops that forced air but you need to seal them to the breather . They were not as efficient as a pro stock but kept the factory style look. My one 69 coronet R/T came with the twin scoops . The first thing I did was installed a lift off Bee hood in 1974. That was my second R/T and came with a Six pack engine Dealer installed new with the twin scoops. All my others had the bubble hoods even my convertible.
