That cam was a Mopar Performance unit, and the sprocket was whatever FWD Performance had at the time. I'm not sure if it was the Fidanza sprocket or not. It's a nice piece, however.
I installed the cam and the sprocket at the same time. I got the adjustable sprocket because the OEM cam has a different centerline than the MP unit, so the OEM sprocket would not have been properly degreed to the new cam. It was a long time ago, so I don't remember the centerline numbers of either cam or the OEM sprocket, but they were different enough that I felt the need to do it right with the adjustable sprocket. I was concerned that I would not get the performance (that's a relative term) out of the cam had I simply dropped it in and lined up the dots. I know it sounds like I was changing 2 variables, but the thing operates as a system rather than 2 parts operating independently. Know what I mean?
