I ordered the SP pump from Summit so I did see the Milodon billet pumps when I was looking. I don't see what would make the billet pump so much better, I mean as long as the machining and tollerances inside a cast housing pump are good, whats the advantage to having the outside machined also. I've seen the billet pumps for Chevies and I know that on an extreme (high RPM Chevy ) motor the cast pumps sometimes break where they bolt onto the bearing cap, but the way the Chrysler pump is bolted on with 4 bolts I can't see that happening. Also, I'm already over budget so fancy candy like billet oil pumps will push the cost up un neccesarily.
