It must have been a really bad "dry sump." Since the engine seized there
as a bad problem.

I think there is far more to the story than has been exposed here.
The bearings are very large in area and if just wetted with oil will run
for quite some time with light load and zero oil pressure. When I worked in the
cabinet shop we had a jointer with 4 knives and a 60 pound rotor to carry them.
It got a few drops of oil each morning, and ran just about all day. It had
poured babbit bearings. It was 60 years old when I used it and is still running
today, 35 years later.
A full throttle takeoff with no oil pressure would do it in with a high
probability.
We did race for years without a windage plate between the engine and the
pan. When braking hard, the entire oil supply would run up into the front cover
and uncover the pickup.
Just a wiggle in the gage would indicate there was much reduced oil
pressure. No damage ever resulted.
Picture is my dry sump layout.
