I remember, quite a while ago, it was desired to have an engine be capable of operating at 10% higher rpm than the optimum intended rpm range.

I expect that percentage is somewhat higher nowadays.

reason was.... better performance.



You are probably right. With all these newer "fast action" type cams out there, the "rule of thumb" for rpm definitely changed somewhat.
