After a month of dealing with an engine issue I was finally able to take the '53 back out today. When I first got in it the clutch seemed to take a bit more effort than normal the first time I pressed it. After that I felt perfectly normal.

Whenever I press the clutch I get a sort of knocking noise. As soon I lift the pedal about a 1/4 or so off the floor the noise goes away. I took it for a spin around the block to see if it still drove and didn't notice anything odd (except for the noise when clutch in).

Here is a link to a video of the problem:
