Call me crazy but it doesn't seem to change with RPM. Or is the video just not picking it up that it does change with RPM? Anything valvetrain related would change the frequency of the knock/rattle with RPM, including a rotating assembly component. Did oil pressure drop any?
Really seems like you have something rattling perhaps not secured after doing the converter swap?

Something loose hitting the cab
of F bodies this is common to see headers hitting the floor, especially with more worn out motor mounts
something to that effect was my first guess

Filter cutter just arrived... I'll post the findings.
Oil pressure has not changed 60psi cold 50psi idle and rises with RPM
I've looked everywhere for something rattling. The rattling sound keeps getting louder and louder. Killing the engine and coasting 60mph zero rattle noise.
I've inspected the flexplate through the inspection hole best I could and can find no cracks.
I've been looking for contact... I'll keep searching.
Circle-D triple billet 3600 stall.
I spent a lot of time getting the spacing correct using the thinner of the two spacers from Circle-D

The filter looks pretty clean. I can see an occasional shiny speck I thought was aluminum but dragging a magnate through each pleat the magnate picked up the specks. My guess it's normal camshaft & lifter wear. I'm running dual .660 springs with a fairly aggressive .629" .615" lobe.
Before dragging the pleats with the magnate

I don’t think that’s enough to warrant concern

Triple disk converters can make noise if the trans pump can't keep up. That's why we use a modified boost increase valve in allisons when a tripple disk is used.
