Here is hugger's card.

I have the card somewhere i'm going to have to dig it up. I looked up the grind number you gave me, it has different spec on it.. however that doesn't mean it wasn't part of a bad batch that comp made of single bolt cams. Here's the scoop i got from my speed shop (Maryland Performance). The owner has been doing business with comp for a while, and they will NOT admit to the general public that they had a issue with a batch of cams, however they did admit to him that they have seen some issues with single bolt cams in with this type of failure are narrowing it down to single bolt grinds between certain dates.. Still there is no way tell which ones are bad, and which ones aren't... till this happens..
Problem is, these pins are not made to withstand the 500hp where demanding from them, a lot of machinist are putting a second dowl in the cam's just to be sure this doesn't happen even on three bolt cams.. Cheap insurance to keep from having this type of failure..
Here's my Cam card btw..
