check the specs on skunks website and then check the ones for CTR cams, if i am not mistaken and given that skunk2 isn't tellin me bull shit, skunk2 should be more aggresive, but hey i could be completely wrong and if so my bad.. but hopefully someone can clear this up cause reving a stock bottom end that high sounds far fetched and ctr cams being larger then skunk2 stage 1 cams
