The photo of the orange engine block is not from me. My block is black. Why would a 6.1 pump be an upgrade and would it fit?

Oh, I didn't catch that. I better back up a little. What 5.7 do you have, '08 down or '09 up? Also, when you checked the ports, what do you have on the filter mount, a filter or block off plate?
