But all of the 55 and up pickups should fit any of the later blocks and not interfere with the no. 5 rod although it does come close. Any chance someone has been in this motor before? Maybe using a pick up from an earlier motor or is your pick up tweaked? Can you post a photos?

Thanks for your reply. My donor motor came from a 57 chevy 210, casting #3837004, so same series as your motor. Your picture looks exactly like my setup. I suspect possibly the person who rebuilt my motor may have tightened the pump to block line before tightening the pump lock bolt to properly index the pump alignment. I'll loosen everything and retighten in the proper order tomorrow and see if that gets me out of this pickle
