I wish Ford power gains would come as cheaply as they do for Chebbies. I need a blower while Chebbies need cams and maybe heads to make similar - or more - power.
Those numbers are not right and not consistent with what independent dynos are showing.
Hemi's are putting out about 250-260 horses at the rear wheel's unmodded.
My Armada puts down 264 horses - bone stock.
When you factor in drive line loss (the Hemi has a notoriously ineffecient drive line and the Titan/Armada a pretty efficient one), 250-260 stock horses at the rear wheels is pretty strong, however.
The 5.4L 3 valve is going to come up about 20-30 horses shy of this. Slap those 4 valve DOHC Navigator heads of yore on the 5.4 and they would wake it up considerably. Especially if Ford follows through and puts the 6 speed auto tranny in the F-150 that is now going to be in the new Expedition.
