I have a 66 Chrysler 300 with a 440 TNT. It liked to eat LH mounts so now I have a chain on it so it can only flex so far. They didn't crack, the rubber separated from the metal.
I had the same experiences many years ago, with the same side motor mount....only it was on a Ford Torino GT 390. The left side mount gets a lot of “exercise” during hard acceleration and/or during towing a heavy load.
