cam bearings What cam bearings are best for a tiny little 4.8, I'm looking for a set but saw a couple options and was curious about coated and regular stuff.
The motor is built the cam isn't stock and will see higher rpms and a pretty good amount of boost...if that helps with the what I'm workin on thing

Clevites are the stock bearings. I have seen more issues with them spinning than any durabond. I cannot tell you how many camshafts I have had to hammer out of blocks with the bearings still attached to them, and not just LSx blocks either.
I am not sure what problems you personally have had with durabond, but we have sold so many sets its hard to keep count, as well as many of the big engine builders using them solely on their LSx builds. Thats literally thousands of engines a year, with no real complaints i hear about. The Clevite are the better bearing for rods and mains, but I trust the Durabond for the cam bearings. Durabond has basically 3 different bearings. The regular, the P which is heavier duty and the T which is the P bearing with teflon coating. They grow in price from the normal to the P and the T bearings as well.

It seems to be more prone to rolling if I use Durabond and the cam installation is always a bit more snug. I don't have these issues with Clevite but then again you may be right. I'm no engine machining expert. I've only been machining them for a year now so I lack the experience that the pros possess but I'll take what I've learned and use that.

I would not have used the teflon coated ones honestly. They can fit a little tight on the cam sometimes with the extra ID that the coating offers. I would only recommend that for a professional machine shop that is used to working with LS engines and coated bearings like that to set up. If the cam doesnt have the correct clearance, you can burn it up. The P series is the heavy duty bearing I would use.
