I like the smooth, streamlined look of your 1979 Brougham.
Happy to share any info you like. I put the whole build online.
I also have a spreadsheet listing every part.

I found your build thread here using a google search.

Between the two doner vehicles (Aspen 5.7L, and A518 overdrive), the trans rebuild, and the electrical harness you are probably into this by $6K not counting all the other miscellaneous. You still had to deal with an electric EFI fuel pump with return (my other option was about $3K into EFI for the 440)
I assume you used the A518 (46RH??) because it was a more reliable (rebuilt) option than the Aspen Trans (which can come as a 5-speed). The 46RH is not electric so presumably an easier install.
With the cost of the electrical, I am wondering if it would not be just as easy (and cheaper) to isolate all the engine/trans controls of the Aspen and move that harness to the Dodge with appropriate harness extensions. You might have to run that harness between the Aspen and the Dodge a few times for fit but you would always have a testbed for the harness on the Aspen.
You would then retain all the OBDII diagnostics of the 2007 Aspen and an essentially stock electrical harness per the factory service manual. I have never done this before. The closest I have come is tearing a rear harness out from cab to taillights to add rear speakers to my 2011 E-350.
Did you use the stock Aspen ECU?
Also I wonder what the difference is between a Truck transmission in the 2007 year range for a 5.7L? Would it be the same transmission?
I would even look at trying to adapt the newer dash to the Dodge RV.
This guy is doing some crazy stuff like putting an old pickup on a mid 1990's chassis complete with dash frame and complete running gear.
