    Yeah, I thought it had a lot of nuggets of wisdom, in helping to understand why one cam performs differently from another. Makes selecting an appropriate cam for your needs a lot easier.

    Russell at NR's info sort of answers why the CL-220 would have a wider powerband, since it has a 105 ICL on the intake & 111 on the exhaust, while the CM has a 108 ICL on both. It is set up to have a wider range, regardless of the lift & duration differences.
