How much is too much

Shame on all those name cam grinders out there regrinding cams to stock lift (and better when desired) and with the ability to duplicate the original profile (or higher performance when desired) WITHOUT adding material. Someone needs to tell them it can't be done.

It is just geometry. Lay the regrind profile over an original profile, then use a degree wheel to check opening, lift and closing at each degree.
