His hard evidence comes from over 40 years of experience which includes using a degree wheel to measure camshafts. It's a pretty well known fact that a lot of the Mopar Performance camshafts don't measure anywhere near what the specs say. I've also verified that very thing many times in the past using a degree wheel. The "hard evidence" comes from years of experience and not given out on a silver platter on internet forums. It will come much better and stick with you much longer if you learn it yourself. Get a camshaft degree kit and learn to use it. They are very useful tools.
