Has anyone ever encountered a cam with undersize journals? I have one here that appears to be .010" down on the others I have. Were bearings ever available to suit?

Thanks in advance.

Mart.

Yes, I don't know how common though, I found a set at Hershey

The .010 undersize cam bearings are still being made and easy to get. Fords minimum dimension for the cam bearing journals is1.7955. When I come across a cam that I want a new profile ground onto if the cam measures under that 1.7955 dimension the journals are now ground the .010 undersize so it can be used once again. I have a few 1932 steel cams with different profiles most of them have been ground undersize probably due to the fact the original 1932 Ford V-8 block did not have cam bearings the cam rotated in the iron of the block.

As Ronnie said pretty common. I have also see cams removed from original engines with.010 under. I also keep under sized bearings & often have cams ground.010 under
