Pre Luber NOW WITH EXPLANATION
I am dredging up an old idea to see if it worth pursuing since I have the parts laying around to make one. The idea is to provide lubrication before any rotating assemblies in the engine start spinning.
Why bother with a pre luber you ask? It is well known that most engine wear occurs on startup. This is because while the engine is not running, it means the oil pump isn’t pumping and the engine oil is draining from bearing surfaces and into the pan. The longer the engine sits the worse this effect. Some have suggested spinning the engine without starting it. That is pointless since bearing surfaces are still rubbing against each other before oil from the pump has reached them. This is where the pre luber comes in. It is a separate device that pumps oil through the engine before any bearing surfaces see relative motions. There are two types of pre lubers:

It is a separate device that pumps oil through the engine before any bearing surfaces see relative motions. There are two types of pre lubers:
- Accumulater pre luber. This is a pressure vessel that stores engine oil while the engine is running and stores it. The next time the engine start sequence occurs, it releases the oil back into the engine. The advantage of this version is it has fewer moving parts and increases the oil capacity of the engine. The disadvantage is that it is bulky and it increases the oil capacity of the engine.
- Electric gear pump pre luber. This is an electrically operated oil scavenging gear pump that pumps oil through the engine during the startup sequence. The advantage of this system is it is compact and easy to install. The disadvantage is that it is yet another electrical device and these pumps aren’t cheap.

You forgot spit as an option 
Honestly I don't think it matters much with these engines. They are one of the most reliable straight out of the box. I think adding a pre luber would just be a waste of time and money and add complexity for no massive gain.
I could understand the thought of adding one on a new rebuild or performance build with tighter tolerances etc. Even then I doubt I would entertain the idea.
As for an engine that's already been run it's whole life over 20 yrs without a pre luber I dont see a point.
Personally I think keeping clean fresh oil up to it is far more important and keeps the engine healthier than a pre luber would

This seems needless to me. Keeping components safe from friction is usually contingent on a film of oil being present. In an enclosed environment like the inside of a cold engine, it'd likely take a long long time for that film to drain away to the point that friction becomes a concern?

How long are trying to make one last?? Lol. On an engine with a lower rotating assembly that known for it’s long life I do not think it would much benefit.
If you think it would a fun project, I would do the electric option. Stored pressure vessels are notorious for leaking down over time. When it does, you have lost its designated purpose. Also, it would be pressurized the entire you are driving it. I would be afraid of a failure and you lose all your oil, even the extra capacity variety all over the ground. At least if the electric one failed, it would not affect truck operability.

You sure do like to over complicate things don’t ya?
97-psd pretty accurately summarized the topic.
I knew a guy who had it on a dragster. Not sure if he still does.
Theory is solid but these things go 400k without bottom end issues so no reason in my opinion. They also won’t fire off without building some oil pressure which means at least it’s not rotating under the compressive loads of combustion.

NASA = space pen
Космическая программа СССР = pencil
This is what comes of one selling one’s business and retiring.

There is a popular urban legend that NASA spent millions developing a pen that could write in space while the Russians simply used pencils. I have obviously chosen to follow the path of NASA's eggheads.
