Another interesting tid bit on the powerplants of these trucks, which is very important of you are to use your truck for towing or offroading.

Ford
4.6ltr: 232hp @ 4750 and 291tq @ 3450
5.4tlr: 260hp @ 4500 and 350tq @ 2500

Nissan
5.6ltr 305hp @ 4900
379tq @ 3600<-here's the kicker, 80% of that tq is availible
@ 1000rpm with 90% being availible before 2500rpm.


So in other words the ford v-8's don't have as much low down grunt and run out of steam up top.

These are 2003 specs before Ford decided to change the power train ratings, as i do not know the 04 specs.
