Update, I pulled the cam out to take a look. I believe the dowel pin was a real tight, possibly damaged, fit. I think the cam sprocket wasn't snugged tight to the cam, and that allowed the cam to walk backwards. I didn't check cam end play last time {silly me} . This time I will. BTW I did check timing with a regular timing light, no difference. Thanks for the brain trust.
