4.2... not a total loss of power...
Right off, I don't see that as a loss of power....
I see Ford claiming that peak HP (202) now occurs @ 4350RPM
and, peak Torque (260) occurs @ 3750RPM.
I see they traded -8HP (from 97 to 07) for +5ft-lbs of Torque (97 to 07).
And really, that seems to be a USABLE power trade. Personally, I'd always trade Torque for HP. It's just more fun.

Not that your going to tell a difference in the ~8 HP and ~10 lbs of torque through the years anyway.
Heck, that extra torque in the 04 plus models is probably more than offset by the added wieght of the new body style trucks...
