when was this? i haven't heard anything about it. I just check the WPO site, and there is no change in the DL world record. The new PLUSA should be out soon, and if he did indeed hit 1003, then it will be in there.
the only thing that I could find was that in November of 2005, Andy attempted 455kilos (which is 1003lbs). he got it to his knees. here is a link to that attempt (his other 2 deadlifts at that meet are on there as well).
