Well, I finally got a response from the King Bearings folks. The 0.020" under connecting rod bearings (CR805XPN020) which I ordered waaaaayyyy back on May-14th, and which have now gone through at least three separate shipping delays (ordered at Summit) aren't even scheduled to be made, for quite some time, as in:

We are currently out of stock on this part and I don't see then going into production anytime soon.

So now I'm somewhat stuck here given that the block ('74 360 casting) is at the machine shop along with all the other parts. The crank is a 0.020" under, forged piece with a fillet, the con rod journals are 2.1040-2.1041. The only undersize bearings I find are stock replacement pieces, which I am not thrilled about using in my build (408 W2 stroker motor).

Any suggestions on what else I could try here?

I thought of maybe cutting the crank another 0.004" to get me to the high-end of the Chevy small block (350) journal size (1.9990 - 2.1000), plenty of choices there, but not crazy about machining the crank.

Is there anything else out there that I could try? Any other stock or even 0.010" under journals in other engines that would get me the equivalent of my 0.020" under, which is 2.1040?

Thanks everyone!

EDIT
My current motor has a SealedPower 0.010" under CP-series bearing, haven't taken it apart yet, but no complaints so far. They do make a 0.020" under as well => 82130CP20
