So you are making it sound like a guy can install only the 2 side pieces of the ductwork on the hood and nothing else? Then run a standard air cleaner like I showed on my blue Road Runner in the pic above?You have about 3/4”-1” of HOOD clearance with a 383 and a 383 airgrabber air cleaner. Going to a 440 airgrabber air cleaner will buy you another 3/4” HOOD clearance. That’s the first part I’d be worried about.
Then if you leave the seal off the center portion of the duct work you may be able to buy another 3/4”
Total stack height first then the airgrabber.
