I don't know what to think, Keith. David is right, that whatever the problem is, 
it must be something that can cool down quickly, which excludes most of the 
internal engine components. Could there be some sort of problem with the 
fan?

Is the engine still tight with the clutch pedal depressed? Yes, takes 2 people 
to check.

I suggest that you check the oil pressure control valves, to make sure they 
are installed correctly, with the right pistons and springs, and are not seized 
in their bores.

Could you get the engine hot and then remove the rocker shafts quickly 
enough to see if removing them frees up the engine? (Or maybe just run the 
engine with the valve covers off long enough to verify that there's oil coming 
out each of the pushrods.)

When you dropped the engine this time, I assume you didn't take it all the 
way apart, so you don't know about any possible bearing problems inside, 
right? But, as Dave points out, how could that cool down fast enough?
