There where some SBC out there that had wrong crank drillings and would shut off oil at Habove 7500 rpms you would show pressure but could not feed rods

Just replace them when I start to feel guilty about running them so long. If you ever build a sbc, call Larry Stewart Sr about buying an oil pump.
