Re: Reground Camshaft

I think the shop is going to change the events on the cam. The shop was trying to provide ways of performance improvement. I told them there is no aftermarket cams available. Sounds like they have done this for customers when aftermarket cams is not an option. My understanding of cam regrind for performance is taking out a thin layer of the base so that relatively, the lobes can produce more lift. I guess the vales need to be adjusted also. This is a just theory to me and I am not all too sure about the detailed geomotry and the outcome. But the shop makes it sound they have done this many times before. I found this on the web about cam regrind.
