Cam Bearings, sigh.

[SBC Maro]

So, in my last thread I asked about which cam to get to support the motor I'm building. Got all my stuff in from summit, and went to work on the motor.

All lifters and everthing valvetrain related was off, and the motor was on the stand as a longblock. Pulled the cam gear off, took off the chain, and reinstalled the cam gear as a handle. Flipped the motor over on the stand to check from obstruction, and made sure the cam had a bit of oil on it to expedite removal.

Pulled the cam out, first set of lobes came out without a problem, second came out fine, third was a bit of restriction, which slid past, then the rest of the cam.
I noticed something shiny on the distributor gear on the cam, and found that it was a sliver of metal.

Running my finger over the cam bearing closest to the timing cover, I felt a large chunk taken out .

So, Can I get new cam bearings pressed in with the rotating assembly installed, or do I have to tear it down again? How much should this run me?

Thanks for your help on the other aspects of this project so far folks,
Rob.
