Everyone puts in a Melling pump. They make some new stuff now, changes in the way the pump works.

HV pumps are somewhat of a misnomer. They make 4 styles, The Chevrolet oiling system works on a bypass on the filter which most do not look at either.

Offerings from Melling:

High Volume, High Pressure
High Volume, Low Pressure
Low Volume, High Pressure
Low Volume, Low Pressure

Which ever your choice, depending on the type of driving expected, I would invest a tad bit of time in the oiling system operation.
