How much is too much

[Tom Wesenberg]

Dick, true that you can grind back the same lift, but now lay a degree wheel over the blueprint of the reground cam and see if you can also maintain the same specs.

I never gave the subject much thought until about 10 years ago when a couple guys were debating the same subject. Marco had a nice drawing showing why it can't be done. Something has to change, just as Marco's drawing pointed out. I'll try searching for Marco's picture, but I don't always have luck finding old posts.
