I also would be interested in knowing, and from what I can gather on most high performance road and race engines, 50-60Ibs Hot at max rpms seems to be normal.
We have a guy here in NZ who races a 62 Galaxie with 427 engine, he blew a few engines years ago but now has it reliable with a modified
oil system and 100psi
oil pressure, but to my mind why would you need so much to keep metal surfaces apart unless the engines arent built correctly.
