Yes, I have completed it. Had a shop drop it in for me, direct swap, everything lines up. Reused the original wiring harness. The L9H has no AFM/DOD so the wiring harness connector for that is left unplugged. Once installed you have to get the pcm re-flashed for a 6.2 and in my case disable CEL for no AFM/DOD signal.
Things to check before you buy.
- Make sure the original wiring harness is the same part number as the new engine.
- MAF sensor must be the same. (Keep original one from 5.3 in)
