But, those were Fords. And sbc = Small Block Chevy, which has a great oiling system, unlike the early Fords. Myself, and many others building small block Chevys use the STD volume pump, modified for LESS volume. I also limit mine to 40 psi @ 8500 RPM. Bearings always look like new. 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.
