I think pushing is a little extreme. For me, I'm still thinking I have the best hand. If you push, you are surely going to be called only by a K or better. I'd raise it a little more than the minimum, say to 350 or 375. If he has the K, he's probably going to come back over the top and you can just fold. If he has a J he'll probably call and shut down at which point I would check behind him on the turn and then call the river bet or bet for value if he checks again. If he has nothing and was just stabbing at the pot, he'll fold to the raise.

I wouldn't be that surprised if he was just firing a bet out with nothing, since this is one of those flops that's usually won by the first bettor.
