To the O.P. Please take full advantage of people asking you to clarify what your question actually is. Its hard to answer a question when your grammer and punctuation are lacking. Also, it would be in your best interests to NOT get pissy with the guys that have been building these truck for over a decade. To answer your question: all the 4.7L magnums are (essentially) the same except for the HO.
