live 300 NL str8 draw on flop

[Weaktite77]

OK so Its a 1-3 live game, 9 handed. Villain is passive and in MP. He only raises preflop with big pocket pairs.

I have ~$340 stack
villain covers

I have 67o at cutoff and 2 limpers (villain is one of the limpers) I raise it up to 18 preflop, and both limpers call, so its 3 way to the flop.

flop comes A58 rainbow
checks around to me. I bet 40, then villain c/r to 140 total, so its 100 to me.
I have ~280 behind.
Hero?
