Currently have Kelford 272's on my FP Red and was looking to upgrade to the Black. What cam is going to be the best for the Black??? I was looking at the GSC S2's to replace the Kelfords. PS I'm also at 5600+ elevation.

 

i hear the GSC S2s work great with FP Black. im trying to sel my new, never been installed and still in the package Cosworth 272s cams. and i plan on going with the GSC S2s with my FP Black. once i get the cams i can finally get this stuff installed!! haha. its killin me having it all sit in my closet.... but i hear the Kelfords work pretty good with the Black as well. search, there are other post about this exact topic.

 

I guess if you have the money burning holes in your pocket you could switch out to S2's, but I wouldnt bother doing so, unless you are trying to squeeze every last hp out of your setup and even then couldnt be guaranteed that you would.

 

It's true, the GSC S2 are the better cam, but if you already have Kelford 272's, i would just keep them. The Kelford's are a good cam and a close second to the GSC S2's for the IX. The few whp you'd gain with the GSC S2's are not worth the cost of the new cams and install...unless you're rich, then yes....DO IT!!! The S2's ROCK!
