Which cam is better??

[8950LX]

I would not change your cam. For the money and time spent you will be disappointed. I have used a variety of cams such as you have described and the difference in power was only noticeable on the dyno. If you decide to change your heads then you might consider changing the cam to complement the more efficient heads. Both cams are great. Both manufacturers measure advertised duration differently,leading you to believe one is vastly more efficient than the other.Remember it's the proper combo that will make the big difference. Hope this helps.
