Standard or Hi volume BBC oil pump question

I wonder how many people here know that the Big block chev high volume oil pump itís much bigger than the standard volume, that a standard volume small block pump and a standard volume big block pump are pretty much equal.
That the Big block hi. vol. falls between the standard and hi. vol. small block pump?
To suggest it's a horse power thief in ether standard or hi volume form would be pure speculation from most.
When someone asks "do i need hi. vol.?" the answer should be "how hot is the oil gona get?" hot oil gets thin, it well move through a system more rapidly when hot, pressure will drop and volume requirement will go up, if volume reserve isnít there pressure will continue to drop with temperature increase.
Metal to metal is gettin to be a big risk.
For those who say "don't bother with hi volume" i say "thatís fine if you never push the limit!!!"
