I was at the turkey rod run this past weekend and bought a Y block 2x4 intake manifold.It is an aliminum manifold and is for the old,small base carbs.It has a Ford PN on the bottom and no other markings. PN is ECG9424-D. Can anyone tell me anything about it? I was just looking for a 2X4 manifold and this is the only one I can find.Thanks.
