These are both BBC solid roller camshafts, and both were purchased between 2012 and 2016, (if that matters). The one on the left hand side is from Lunati and the one on the right is from Bullet. The one on the right looks to be made with two different alloys, as though it's a two piece core. But I don't see why it would be, nor how it could be. Can anyone shed any light on this for me? Is the different appearance of the Bullet roller cam on the right any indication that it's made from a different core material? And if so, is that better, worse, or just different?
