Has anyone ever seen a 54 New Yorker with the " Heavy Duty " package ?---dual 4 barrels along with some other modifications ?---I think about 14 or so were ordered with this package----I have an air cleaner here which is exactly like a 55-56 300---I know they are slightly different---except the collars which fit on carbs are almost 2 and one half inch's deep----this unit would never allow the hood to close on a 55-56---but the hood on a 54 would most likely close with this air cleaner installed-----I am wondering if this unit is from 54----Johnnie Slayton
