All of the benefits make sense. Look at it this way....a Whipple supercharger with it's helical rotors is much more efficient than a roots blower with very little to no helix. The Whipple moves more air, seals better, doesn't take as much power to drive, etc. All of those can apply to the oil pump.

They will not have a design for the BBC. The SBC pump is a 7 spur gear pump vs. 9 spur gear for the BBC. The torque and pressure ripple are more aggressive in the 7 spur design. while they are significantly dampened in the 9 spur.
