Not sure what I am seeing on this cam

I have no idea how much time is on the cam, the 340 was in the car when I bought it earlier this year. It seemed to run okay, but this jumped out at me as soon as I took the intake off and looked cam-ward. I figure it's not right, and the engine is getting torn down, but I know now I won't be re-using this cam, that's for sure, or the lifters. May be time to go to roller cam/lifters/rockers.
