NL 50 over pair against a big over bet

[Tony Montana 22]

55/1/.25/250
Villan is very loose passive, does this huge overbet thing when he thing when he thinks he is good, not as a bluff.
He did it before when I raised ak and he cold calls pre and does this funky overbet rr on a kxx flop and turns up with AKs.
I do not see him doing this with a draw ever and think I am going to see 27, 62, 67 or a set way more often than something i beat.
Does anything change if the flop were say a 9 or T high?
