Dargo said:It should be a no-brainer; wait and get an '07 F350 with the vastly improved 6.4 diesel. First, I have an Expedition with the 5.4. It can't pull itself along a highway that has any hills without constantly downshifting!Hooking up the kind of weight you are talking about behind a 5.4 liter would be a very, very sad situation. If you go up any hills, you'll have bicycles passing you! On the 6.0 Ford diesel...er,...uh,...I can't think of one single positive thing to say about it. If you can't wait for the 6.4 (it should be a hint to you that the 6.0 diesel didn't even have but a 3 year run), buy a used one with the 7.3 diesel.
Myself, since I pull heavy all the time, I had no choice but to go with the Cummins and spend some serious bucks on a bulletproof aftermarket tranny to go with my juiced Cummins.![]()
Couple of things to remember if you do go with a 6.4L(even though its not a listed option)... The 6.4L will be an '08 released EARLY '07.. So, if you are inclined to go that route for the specific reasons or getting a 6.4L, make sure thats what your getting(shouldnt have to say that, but you never know whos listening
As for the 6.0L, I've mentioned it in the past, but its not going away because of problems.. That may be conveniant, but not the reason why.. The 7.3L would not pass '04 emissions.. The 6.4L was not ready(common rail fuel system), so the 6.0L was designed to fill this time slot for emissions purposes.. The 6.4L was needed to pass '07 emissions.. The '07 currently being produced have '06 6.0L engines in them to meet this critera, the 6.4L will be its replacement for emissions purposes.. Obviously, everyone is expecting the 6.4L to be flawless(as much as possible) to help counter the reputation that the 6.0L has gotten(some deserved, some not)..
Dargo,for what you wanted and have done, you made the right choice.. The Cummins is awsome, no doubt..But not everyone needs a 1000ft lb engine to tool around in.. I know you have some kind of background with these things and see some of the failures, but trust me, I see my share and can promise(anyone who cares) that a large number of these failures are from neglect and abuse(ie: chips, programers, other modifications, oil change intervals,fuel filter intervals, overloading, excessive idle times) that this engine cannot handle.. In stock form with proper maintenace, these engines can go a long way... I'm just adding this point, again, to give a different perspective from the anti 6.0L group.. You may notice that several guys here have 6.0L's and are happy with them..
