Well, the SRT is done. I had a pesky check engine light that I thought was in the "turn off MDS" tune. Come to find out, you gotta plug the camshaft oil actuator back in after deleting the MDS. I dug the harness out of the trash and plugged it back in. All good!
The transfer case had the way too common issue of a knocking sound at idle when shifting from D to R. Does it for about 5 seconds and stops for a while. Also, it was binding up when turning. A new Transfer Case Control Module (FDCM) cleared it up. Luckily, SRTs are so common (sarcasm) they give them FDCM away (more sarcasm). But it's fixed and totally done.
Definitely glad I decided to rebuild the engine instead of buying a long block. Saved a bunch of coin and I know 100% how it went together.
