Friend of mine has a blown 5.4 in a 2009 F250 and wants to swap it for a FREE 5.4 out of a 2007 F150. I said don't believe it's a straight swap and there are lots of other factors besides the older engine being a 5.4. Don't know that as a fact but would like to know what's involved and how much money is he going to spend to make this happen. Any info is most apprecited. BTW I own a F150 and know very little about 250's.
