I don't think trying to eliminate stacking tolerances is "creative marketing"
It's been around since the industrial revolution*
*edit* since man has been measuring things...lol

Since all cams are made on machines I find it hard to understand how tolerances can be so loose that calling it Billet fixes the bad tolerances.
Not meaning to argue but, really, what is the difference and why is the difference better. I don't buy the better tolerance point.
Ford roller cams last hundreds of thousands of miles and with the accuracy needed to meet emission regulations they need to be darn tight.
