I was looking at the Ram Air Flapper of a Hurst Olds, stamped steel flapper door, stamped lid, shaft and pneumatic valve actuator. I could not get over how these parts looked identical to those on a FORD Shaker lid or the breathe through the scoop lids. The guy obviously catered to Hurst/Oldsmobile muscle. I asked him about the FORD Shaker/cold air parts resembling the Olds stuff he had displayed?,,,,, He said you are right Hurst/Oldsmobile and American Motors both utilized FORD parts in their through the hood breathing combos.
So thinking back and "searching" I'm guessing the "ram air" air cleaner components may have been unique to HURST/OLDS (not Olds) and if so perhaps the guys at HURST simply went down to the Ford/Mercury dealership and purchased SHAKER lids and cut them up to weld on to their own filter/ram air housings?...... Hurst I presume was modifying "stock" Old's like SHELBY, so they not feel guilty using parts/components from the FoMoCo dealer. Pretty amusing that Hurst/Olds and AMC (perhaps AMC/HURST?) were putting a hurting on FORD Shaker/Ram Air components in the parts network. If you see one in person you can notice how they amateurly rough cut up the FoMoCo covers and melded them on to their own covers.
