What oil pump to use?

@moper You bring up some important food for thought. The stroker kit I have is from 440 source. They package everything together with what I thought was good components with respect to bearings. The machine shop did the main bore and measured (miked) the components. I will redo the measurements myself before proceeding. I found a really thorough article that helps with bearing selection and concepts of oiling. I skimmed it but I will read thoroughly before measuring this weekend. Thanks for the help @moper. I want to assemble this once correctly.

The issue, if you're using Source parts, is that the clearances will more than likely be all over the place. And THAT, is where things get messed up. Source parts are "good". They are not "great". Things like taper and journal size will vary journal to journal, and it's hard to plan and say "it will be fine" when one clearance is factory min and the next is a hair over factory high. Welcome to that price point...
