I have noticed that the Power Pack on the same year 4.0 engines are placed different, some up front on the right and some in the back right hand side, why
i am looking to up grade my 2002 Sport Trac engine to a newer year engine. When i look on line at the engines available i notice that some have the power pack in the rear of the engine and some up front on the right will this make a difference in my choice of engines. I would love to put a 2004 or newer, Any comment or suggestions/
