Stock block cam Bering hole diameter?

[Bored&Stroked]

Hey Ronnie, the cam bearings you're speaking of are for a cam that has been ground .010 on the bearing journals - like original Potvin 425's on 32 billet cores.

I don't believe they are related to the OD of the bearing and block? Are you saying there is another set of CAM bearings that are .010 under on the OD (block bore)?

I've never seen that. I have seen some that are LARGER on the OD . . . probably to fix blocks that were screwed up during initial manufacturing.
