I read the article. Pretty interesting. One thing that bothered me (and I get it...it was testing for a magazine and they don't have a ton of time) was they didn't even move the cam timing at all to see what happened.
I'd have loved to seen what would have happened if they took the MP .620 and installed it at 101 or 100 instead of the 104 they stuck it at. Even 102 would have let you know if you were trending in the right direction.
I also noted as the cam timing was changed to make the overlap triangle steeper and more pointed the power curve changed. It took more timing to get the same RPM, but the bottom and middle numbers were better too.
