I have no idea what the castng numbers mean. Get a micrometer and do some comparative shopping with what you have. I installed the cam that the highest lift, and also the most consistant lobes of my bunch, for what it's worth. I have an R1 and an R8 still sitting on the table. The R1 still has a '89 - '93 belt gear installed. Origin of these is unknown. |

Didn't even know they had numbers on them, no idea. That could easily be just the mold number and meaningless in regard to what lobe was eventually machined into it. Standard cams have a 40.5 mm lobe height, XFI cams have 39.5 mm and a slightly sharper point. |
