I found it, I'll send it to you....actually, lol, it was 660 for 10 singles supposedly......I actually find 600 to be very believable for a world class olympic lifter or shot putter, most people generally tend to question this claim, I don't know, It'd be awesome if it were so, and Louie is a credible source, I guess nobody will ever know, just one of those things that becomes 'legend'...in any event, Udo was ridiculously strong, he threw the shot over 74 feet, and that certainly was documented.
