Thanks, elgyqc! In this case, I'm aware of the LN retrofit installer's identity. My quest is to determine why the engine has the later-model IMS complex (including crankshaft!). I've now determined that the engine was completely rebuilt by an unknown shop using later-model parts in place of the originals.
