I have no idea why the high volume pump idea wont die. With new bearings recommended at the same time no less.
Because he's slapping new bearings on worn out journals. This is the application hv pumps were intended for.
No, that isnt what a hv pump was ever for. New bearings should bring up the pressure with a standard pump. I wouldnt bother changing them unless they were real bad anyway. At that point you'd likely want to polish or cut the journals, which also raises pressure.
A hv pump is a crutch for a trashed, ragged out engine. Thinking new bearings go hand in hand with one is wrong.
