I am not sure about the diesel. It looks like the availability of the 5.0 early 2010. The 4.4diesel line is up, from what I have heard. But I do not know when the production start date is. Essex is to be up in late June 2009 for the 5.0. The crank department is running now suppling Romeo plant for the 6.2l engines. Romeo is building 6.2l but I do not know what they are going into. The Harley Davidson F150 had one at the Chicago show.
