$80 HUSNG, Does Villain ever fold a (bad) boat?

[NSM]

Villain not overly stubborn. Haven't played any big pots yet. Is this a bluffable spot? How many villains fold a 3 here? Part of why I ask is I often overshove a K or the nut 9 in this spot and feel like I run into a fold 2/3 of the time. Wonder if villain is ever folding the 3 in these spots or if I more likely had stubborn opponents w/ A or some funky "draw".

What's villains threshold for pain with the bad boat? Does he stack off here? Is this not a profitable spot to bluff?
