For all those that think 4 hole adapters to Q jet intakes "kill flow" personal at track experience. San Antonio track my 455 with E heads small roller had a 72 HO intake and a Brad Urban 73 SR SD Q jet 800cfm that ran good to keep the Shaker until I modified an extra base to clear the Holley/Demon bowls(front a BFH rear esp Holley I grafted a piece off a cheap drop base air cleaner). So at the track swapped an adapter and an 850 DP Demon out of the box the idle was right on and it picked up 0.2 seconds an 3 mph. So I guess it did not hurt flow that much. Eventually swapped on a Torker II that picked it up a bunch.
