Tough Spot in the 1k with a pair + a monster draw

[Eagles]

So far I've been playing pretty tight, haven't made many moves etc.
Villain has been playing very aggro 3betting a lot one hand he 3bet the pfr with 34s and showed down his pair of 3s which beat the other guys Ace high. That said most of the time he has shown down a hand he has had it and despite his agression he isn't an idiot. Seems like a pretty solid player.

Blinds are 100/200 I have 9.6k he has 9.1k

Folded to me in the SB I make it 600 with AdTd he calls.(This could be a very wide range of hands)

Flop is Qd As 4s (1200)

I bet 800 he calls

Turn is the Jd Pot is (2800)

My line?
