You seem to make a lot of inflated claims. I'm beginning to think you are full of shit considering your build, which is in no way impressive.
I am actually Kevin's height which is tall for this game.

My max single so far that I have actually achieved is 345, everything beyond that is pure speculation. I think I can do a little more than that considering I pyramided up that day, but that is just a thought, nothing confirmed at this point. Max for reps was 225X21 with decent form, on video, 17.
My max deadlift is in the upper 400s depending on the day. Not close to 600 yet.
