Would it not be the same like when kenne bell was selling supercharger kits for the f150 and expedition. I ask because a friend found a HD engine for me for cheap but all it is, is the engine with all pullies and brackets but no computer or IC stuff. My F250 LD already has an E4OD so really I believe I just need the new style heads and the pulley bracket bolts since I plan on going with a MP pulley bracket and Whipple 3.4 of my buddies old engine.
