Anyone know HP and Torque for 3 valve 5.4 vs. prior motor?
Hi,
We have a 2000 Expy 4x4 with the 5.4 and recently upgraded our horse trailer to a larger (and heavier) one. My wife loves her truck, but it's feeling a bit weak with this new trailer.
Could someone who knows, post the HP and TQ values and what RPMs they peak at for the earlier 5.4s vs. the 3 valve 5.4s (which I think came out in '03). We're thinking about upgrading her to a new or newer one. (Or maybe I should just research superchargers?!
)
Thanks in advance...

Information for the 2000 Expedition:
Beyond the choice of two- or four-wheel drive, the buyer also chooses between two V8 engines. The 4.6-liter and 5.4-liter V8s are identical save for displacement. They are smooth and quiet. Both engines are mated to a four-speed automatic transmission. The larger 5.4-liter unit delivers extra pulling power for full passenger loads and heavy trailers. The 5.4-liter V8 produces 345 foot-pounds of torque, enabling it to pull a trailer of up to 8300 pounds when ordered as a 4x2 with 16-inch wheels and the 3.73 axle ratio limited-slip rear differential ($255). An Expedition 4x4 with the smaller 4.6-liter engine and big 17-inch wheels can only muster 5500 pounds.

The Expedition did not get the new 3V 5.4L engine until the 2005 model year.
2000 2V 5.4L: 260 hp at 4500 rpm with 350 ft·lb of torque at 2500 rpm
2005 3V 5.4L: 300 hp at 5000 RPM with 365 ft·lb of torque at 3750 RPM
2000 2V 5.4L: 260 hp at 4500 rpm with 350 ft·lb of torque at 2500 rpm
2005 3V 5.4L: 300 hp at 5000 RPM with 365 ft·lb of torque at 3750 RPM
