You need to look at the oiling system.
A good pump is needed to make it live a long happy life. Then the pan becomes a issue. A stock f body pan pick up is bad.
I prefer to run a HV pump from the Car Shop Inc. These pumps have a few things done to them that eliminate volume issues.
Then the pan needs to be looked at. the pick up loction needs to be correct along with the screen most are to restrictive.
Here is a screen shot of my oil pressure in a run. The high pressure is not a issue and the engine has been very happy like this. Few of car shops other customers have several 100 passes with the same set up and no engine issues

I run a good Wix R filter that will handle the pressure.
The crank turns the pump so it is not that much of a power issue.
These engines need oil volume to get this the pressure has to go up. Only way around this is dry sump$$$$$
Granted if I could get the volume and oil where I need it with less pressure it would make more power but what 10-15 hp is not worth it when it is burnt up.
