One more heat susceptible thing, not related to fuel, was the TFI
***Link Removed***. Ford used it in the 80's and early 90's. I'm not sure if it was used on the 460 engines but it's highly probable.
The short story is I ran into this with a 1990 5.0 engine that worked fine previously, then sat around before it was installed in a hot-rod. The engine consistently ran poorly when hot and was even hard to start.
Usually the fix was to remove the module from it's mounting on the distributor and put new thermal paste between the module and a heat sink on the main distributor body itself. Apparently the thermal paste dried out from either time or inactive use.

When the car is driving, the engine is heated. And if the heat sinks above are not given to thermal paste, the sink is dried by heat. And that's their problems created. So between the module and a heat sink, use the thermal paste.
Thanks for the solution.
