It’s not a paperweight, but the journal is significantly weakened. GM has always been bad about having thin fillets on rod and main journals. I can’t tell you how many GM cranks I ground that had next to no radius on any of the journals. What you need to do is take the crank back to the machine shop where it was ground and bring it to their attention. If it was ground ten under they should be able to correct this flaw. If they won’t take responsibility for their FUBAR find another crank grinder who will.
