im not going to deny the possibilities of stacked tolerances compounding into a dramatic end result and the best way to combat this is to degree the cams at the source, but no street car or moderate track car will benefit from the science level some of these people take it. If MHS claims tolerances with their degree service, you can take it to the bank.
Watching "that guy" all these years, always late to the game, give it another 5 years and he will start offering a cam degree service. He always has to back pedal his words. Besides all his customer base is the FB kids.
MHS has grown a successful business based on its founder Nick McKinney. That guy had things figured out!
