87-93, it felt like it had some power, but was not a 5.0. He told me a few times that it wasn't a 5.0. It had factory T-tops, so I'm not sure if that pinpoints the years it was from, but I know it wasn't a 4 cyl. Maybe someone before him swapped a different engine in there, but why wouldn't they swap a 5.0 in there if that was the case.
