Default Cam Carnage

Has anyone seen anything like this before?





Weird thing is all of the lifters look fine. No signs or irregular wear or anything. I measured the base circles of several of the lobes ant they were different. 1.390 on some and 1.425 on others. Is this normal? Any input would be great.

Yes, sadly many of us have pulled out cams that look like that. Many different opinions about what may have caused it ranging from improper hardening, insuficcient spring pressure, improper cam grinding or polishing, etc. F-13s had a bad batch last year and allan is replacing some torn up cams. if thats an f13 contact allan and see what he says.
