I know you didn't, I agree with your CR theory, its just an example of how you can do it on low cr when you do not have a full on race engine designed. It all comes down to use. Although it can still be done on high cr if you pick the right cam for some street use as Dom and others have shown within reason, we can all put up with a full on race motor for a while on the street but this thread is about a street/strip build, down to the owner as always and where his mentality is.
