Not Ranked
Cam selection is really more judgment and experience than anything. Bumping up durations or adding more lift won't do squat if you've reached the capability of your cylinder heads. You end up moving the hp out of the range that can be used and not gaining anything.
As for engine sims, a 7-8% difference can be quite a bit....more than 4-5hp.
