If you have the cam's detailed specs, PCM Performance can handle it by email as well.

It's the OEM factory external transmission oil cooler. RPO KD1, standard with all LT1 sedans (and non-KNP wagons).
Transmission oil is BOTH internally warmed and then regulated by the set of lines that go to the tank on the radiator's passenger side, AND THEN externally cooled by that cooler.

So far as I know, only 9C1 sedans and 1A2 wagons got external engine oil coolers.
All civilian LT1 cars got engine oil routed to the driver's side radiator tank.

You may want to consider separate winter and summer setups?

During hot summers that demand constant MAX AC, trans oil does not need to go thru the radiator sidetank, but the external trans oil cooler is absolutely necessary. It's actually a great idea to upgrade it, add a fan to it, or both.

During winters where an OEM 180°F thermostat and GM's pretty hot fan-on thresholds actually become a great idea, the OEM arrangement is ok. You may want to consider a 195°F thermostat when it approaches arctic.
Some people even block off airflow to a small portion of the radiator. Maybe you'd only need to block off airflow to the external trans oil cooler.

Hope you plan on some kind of heat management coating for those headers ...

Regarding Barrett's esophagus, you may want to ask if it's too late to consider a
Hill-Nissen fundoplication
or a
Hill fundoplication.

Also, checking every three years seems like it might not be often enough?

It looks like those procedures are aimed at limiting acid reflux, but Barrett's cannot be healed.

What happens is the normal esophagus tissue changes to become more like intestinal tissue.
There's no way to change it back, at least not at this point in medical history.
Meaning, it's too late, then. OK, that part sucks.
Hope those far more qualified than I manage to stay at least one step ahead of your situation.

Am I crazy for thinking this might look good on a Fleetwood?

View attachment 207358
If you are, you can always try it in such a way that we need never find out about it unless you go out of your way to post pics of it.

The Fleetwood's style is art-deco, conservatively evolved.
That spoiler contrasts because it is clearly not art-deco in any way.
Whether or not that contrast is clever gawdy gauche or repulsive is in the beholder's eye.
