torqhead,
The tech that Paul has looking at the motor pulled the plugs wires one by one and the knocking noise remained the same. Here are some pictures of the bottom of the motor when we had to add spacing to the windage tray (First time we pulled the motor).

I also added a picture of the oil pan. I took this picture right when we packed the motor up and it was sent to Arizona a few months ago.

Has it been run with the valve covers off? Or a cover with an opening to hear if it is prevalent to one side?
Is the noise louder at low rpm or just drowned out by other noise? I’d look to eliminate any noise you can....exhaust especially! It may be louder (or not) at increased RPM....and therefore more discernible.

I really think if parts were interfering they would ‘self clearance’ by now, or be producing a lot of shrapnel.
