Cam regrind - how is this possible
I often hear about cams being "reground" to change the profile. I just don't understand how this is done.
If you want smaller lobes with the same timing, I can see how you could grind down to a new profile. But when people regrind, they are usually looking for a more aggressive cam. It would seem that you have to add metal to the existing lobes to make them larger. Even if the term "regrind" is a misnomer for adding metal, I can't imagine how metal would be added to a cam lobe. How can this be?
