I'm trying to identify my engine. I have a 360 in my 1979 wide track cherokee chief. It has an Eaton power steering pump and it was only after owning the cherokee for about 16 years that I realized the engine wasn't from a 1974 Cherokee as I had thought. I concluded it was from a 1971 Javelin (its new claim to fame!!). Does anyone know when and if Jeep stopped using the Eaton power steering pump? Could it be from a 1972 Wagoneer? I need this information so I can purchase the correct long block. (The engine ID tag has fallen off the valve cover) Thanks.
