Oil pumps again...

They were all stock type except for the Milodon. When comparing them all to pressure, volume and HP the HV scored the best at pumping gph and maintaining pressure. The hp thing was a non-issue.
Im actually curious how Milodon billet works with stock type pump cover vs HV pump with stock type cover. When youre lookig for a pump its usually rotor part thats gone, rest is good so in reality for billet pump you need to spend 50-60$ more. This is why I'm asking but from what youre saying its a waste of money... I have a few stock covers to try with Milodon, but at this point spending 200$ for this experiment seems stupid.
