I had a few similar hands yesterday, lost a few buy-ins against sets. On the other hand, I was tilting a bit. To me, it seems a bit like either AT or TT, maybe 77. I'd feel a bit unsure of this play, either way. And considering your opponent being 40/10/3, he could've called you with a weaker ace and hit two pair on the flop, no?
