No oil pressure post oil change (with pics). Any ideas on what happened?

[Gsmopar]

Problem solved! Recommended intermediate shaft and installed shaft were different lengths. Pump primed and fired up with more pressure than it's ever had at idle. I let it get to ~110 before shutting it off as I thought the pressure was excessive (it dropped once it warmed up). Per all the comments above; I contacted Milodon about the torque specs. I was told "Spark plug tight. Snug plus 1/4 turn." Also from the above comments; after following the Milodon directions, I spun the pump by hand with a screw driver and intermediate shaft with no gear. Next I spun it with a drill and monitored oil pressure. Several over precautionary steps in between and it's happy!

You have a roller cam, correct?

Yes

This highly depends on the filter used and if it has a by-pass or not. I was using a fram HP1 with bypass and everything was contaminated. Now I use a system one filter.

You will learn in time.
