Default rod bent??

well i just want to throw this question out there cause its bothering me.i spun a rod bearing 2 months ago so i had it rebuilt new crank,rings cam,heads were done bearings etc, i drove 500 miles after having it rebuilt and it started knocking like hell so i was pissed contacted builder and he said i over revved it which i didnt so took engine out brought to him today he will take it apart this week or next and let me know so im hoping something minor i thought maybe a lifter was stuck or valve, but i drained oil it was copper silverish color so i got scared and ruled that out. heres a link of what it exactly sounds like just a little more hollow sounding.any ideas? would be helpful. http://www.youtube.com/watch?v=pVA4eedOYTQ

Sounds like a Spun Bearing..and with the silver-copper flakes in your Oil that is pretty much a key id of it.
