Have you ever priced out a J drivetrain? The factory headers were J and Ram K only. Short rams the same. Carbs are unique. Block is unique. Just saying even though the seller is asking a lot, the drivetrain has some serious value.
Man, you gotta feel for John. Not the 1st time he has issues, he had a fire years ago at his old place I believe when he was in Reno. Plus a big flood in Williams about ten years ago. John is one of the nicest guys you will ever meet, willing to give you the shirt off his back.
Looks like no notes on the bottom of the build sheet? A CHP car usually has "California Hwy Patrol" or something similar on the bottom of the sheet. There will also be a lot of "99" codes on the equipment list because of all the special order CHP specific parts.
You would think a L Code Fury four door would be a police car but this isn't. U/1 on the fender tag means someone sat down and ordered it. 26" radiator without air means it was ordered with the towing package. So you start to get a story. Cool rig!

Same car sold at Barrett Jackson Scottsdale this year. Check out the intake clearance on the pass side inner fender...they cut the fender to make the Ram intake fit.
I know of one other 4 speed 64 Chrysler 300 non-letter car, I am sure there are more out there but its pretty rare. I haven't seen any production numbers.
On your dealer question, it was probably a dealer trade. The 1st dealer probably couldn't sell it so they traded to another dealer...
