My 4.6 must be out of spec because the 5.0 had much better power for towing and regular driving. The transmissions and rear ends are the same for my 91 and my 99 and they are both 4x4. I'm selling the 99 to find/buy a 87-91 F150. I just like the older ones better.
good call... its rated for higher power but the power comes in at a higher rpm. if you keep the rpms the same the smaller displacement will make less torque- which is what you feel.
