Solid cam damage diagnosis help

I wasn't looking for a freebie. I want to learn from the situation. I had already ordered the replacement cam. I just called once again and spoke to Tim. He did glance at the pictures and was referring the situation to their cam tech. I was very upfront with him this morning of the situation. Like I said I want to learn and correct the situation. I hope they are equally forthcoming if it's determined it a bad grind. I just want to know. I am really going to try and locate a lathe to check the taper.
If you're honest with Tim, he will bend over backwards to help you. He does stand behind his products and understands sometimes parts fail.
Good Luck
