Im kinda confused on the hp ratings and when they were changed. My friend has a 99 Exp. with a 5.4. He says his owners manuals says it is 235 hp. I thought 99 's got a boost in hp to 250 or 260? Found some info on the net and it states that the 99 Expedition 5.4 has 260 hp. help guys. thanks!

 

99 was the changover date for the PI heads and 260hp on the trucks, early 99 Expy's may not have gotten the new heads. Look in the fenderwell at the heads and see if you can find a PI stanped in themm, if so, then it is 260hp, if not then it is 235hp.
