Cam bearing- would you run it?

Remember cams run at half the engine rpm.

That said, if the block is out and stripped down I'd just replace it since it won;t get easier or cheaper than right now.

Yep that is more than good to go. factory or rebuilt engines can get that kind of leading-edge damage from cam install alone....much less form wear. And the facing surface of the bearing is evenly worn. One should only assume you are to be running a high-volume oil pump after whatever work you do to the engine if you were already. And to of course be running Valvoline 4-stroke ATV engine oil afterwards as well as that is the only one with zinc in it to properly lubricate a flat-tappet cam and lifters, etc.

Hello and thanks for the replies.

This bearing is supposed to be new, it just looked pretty scrubbed to me. All the other bearings you can tell are new. This one looked suspect though. The PO slid a couple cams in and out and maybe thats where the wear is from. A brand new CC camshaft turns freely, so I guess I'll leave it alone.

I plan on using a high volume oil pump, I was not aware ATV oil had high zinc content. I usually use Valvoline synthetic racing oil and zinc additive, but man, it's pricy. I think the last oil change I did on my 440 with a premium filter was right around $100.00

That will be fine, I have run much worse with no problems. Simply "fitting" a new bearing to the block can look much worse than yours.
