a 5.4l computer, wire harness and vaccumm lines are needed. 5.4 motor mounts bolt right in. I've never done the switch from 4.6-5.4 but my friend has done two. I went from the 5.4 to the 6.8 V10. the mounts are the same the engine was a bit longer so i had to go with an electric fan. it has all the power and torque i need. the engine was cheaper than a junkyard 5.4L. came out of a E350 ambulance and had 15,000 miles on it. got it for $1,200 plus computer ,wiring and vacc. was well worth the 2 1/2 weeks of work and bummin rides
