This was a 4.6l Expedition XLT. Last Christmas the engine locked up on us going to New Mexico. I bought an Eddie Bauer Expedition that was wrecked and took the motor out of it which was a 5.4, Perfect, now I got an upgraded motor. I completed the swap exactly a year from after. I'm still working out the tweeks and kinks. Theengine runs good but the computer has to be tuned. After I finish the engine work, I will begin with other projects for this beast.
