I would like to see how this works out for ya. I could not see that cam making great power at 7K. I am guessing this is just were is starts to float the valves. It looks more like an idle to 5,500 RPM cam. I know cam recommendations are not 100% accurate thought but more of a guide line. With cars a cam that says 5,500 RPM might be good to 5,500 RPM in one motor and 6,500 RPM in another of the same CID depending on how they are built.
