I am looking at replacing my 99 F-150's 4.6L with a 5.4L. I just bought a car trailer and I'm looking for a little more power. I am willing to trade my 4.6 with 119K miles plus cash for a 5.4. You can hear it run in my truck on youtube and chances are if you have something I'm interested in I'll be picking it up in my truck. You can inspect the motor then.
