I am currently putting a bbc 555ci n/a carb gen 4 motor together. I came accross these cams on CP Performance web site http://www.cpperformance.com/c-1501-...sion-cams.aspx. I run the KE aluminum long manifolds. Im not sure if I would even need the ant-rev cam.

Is there some wierd installation process. I allready have the 9 position timing set.

I am thinking of running the stage 3.

Any input would be appriciated.
Thanks

Their just saying you will need the 9 position timing set in order to "degree or sync" the cam with the crank for proper installation of it.
