Dead mans hand

Busted from the bellagio 540 nl halfway through the field. I won a few pots early on with top pair and a set of 7s. Then I went completely card dead for an hr. With the blinds at 100/200 with a 25 ante I was down to my last 2500 chips. I was in late position folded to me and I find 2 black 5s. I made it 1000 to go. The big stack on the button with 8000 or more flat calls the raise. The blinds fold and we see the flop Jc8c8s. I went ahead and moved in my last 1500 hoping he missed. To my surprise he called me with QhTd. The turn was the Ad and the river was the As. Any comments on the play of the hand are appreciated. His call of 1500 in a pot that contained 550/1000/1000/1500 or 4050 gives him just under 3 to 1 to hit 10 outs if he is sure they are all live so I suppose he was correct in calling.
