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.
