How would you see a fight between prime Marciano and various versions of Cassius Clay/Muhammad Ali going? If you would like to humour me just for a laugh!?

I actually wouldn't be surprised if the tough Marciano could find and knock the skinny gutted Clay out. If Henry's hammer could find him, imagine what Rocky might produce.

However the Muhammad Ali that got the rightful champ of the 70's in a huge upset (Foreman) circa 1974 would have punched the shit out of your precious Marciano, and I don't even rate HIM that highly.
