milodon hi volume oil pump

I bought a hi volume Milodon pump. It came with the Melling part number cast right into the body of the pump. Melling will forever be good enough for me if I'm buying an iron body pump.
Melling is what I`m running, kinda suspecting it a little , no real proof, but don`t ''really''
want real proof !-----LOL thanks, The pump I`m looking at has an alum. body, hi volume , would have to use my external pick up plate and stuff on it.
