There is also an nice discussion about the effect of too much overlap on exhaust gases and how they may replace some of the fuel mixture and also have a detrimental effect on heat dissipation.

I was a little confused at first because there is Elgin Industries which Dema Elgin started and then sold to it's employees, which tends to make budget cams from what I have read. Then there is Elgin Cams, which is the new business that he started focusing more on custom and race cams from what I read.
