Default Oil filter leak on 428

I got my pulley alignment worked out. When I went to start the car, I had a major oil leak that was collecting on the top of the filter. I thought that the filter might be bad or that there was a leftover rubber oil gasket. I replaced the filter and the same thing happened.

Thinking the oil filter housing might be cracked, I replaced that but I still was getting a leak. I took a video but can’t seem to upload it. The leak starts at the back on the left and then just pools on the top and runs down the filter.

Any idea on what to try next? I ran this 428 for about 10 yr and it never leaked oil before. The oil filter housing gasket is new. I am running 20W50 oil. My oil pressure does seem a little high at start up (65 psi) but I can’t remember what pump is in this engine. It is definitely a Canton pump that came with the pan.
