difference between these two cams?

Another thought - Making good horsepower (or overall power) is not just the power you're trying to create. It's about minimizing the power that is required to keep that crank turning, and the rpms it's capable of reaching. More rpms will always equal more horsepower because there's more firing events per minute right up until valve control or airflow is maxxed out. You could have the same lift, total duration, and duration at .050, and still have a bit more duration at .200, but the lobe is shaped more like a square than a triangle, so the spring required is much stiffer in order to maintain valve control. Those differences can be significant, and the power enough to measure and potentially feel.
