Cam gone flat? Here's a interesting video.

Where it hit home with me isn't the hardness of the cam or lifters that is the issue. There was two things.

1. Using PROPER break in oil and PROCEDURE
2. The cam/lifter QC isn't what it used to be because it doesn't have to be (no need to supply oe) he mentioned the taper of the cam lobe and the flatness of the lifters.
