I think you gotta call this flop, being in position and all. The goal here is to neuter him by repping quads (you would flat call here with 45s, no?). I'd probably fold if he continues on the turn, but continue the quads repping by making a bet on the turn that will lead him to believe you might just be planning to push the river. If you call the $150 on the flop and bet $400 on the turn (leaving him looking at you with $1170 to bet into a $1110 pot on the river if decides to call), overcards certainly ain't about to get funky with you, and even hands like 55 and 66 shrivel up. I'd be inclined to check the river if he calls the turn, but I could be persuaded to push the river as a bluff for any number of feel-related reasons.

Also, it's ok to raise the turn as a bluff if he bets. I'd just like to point this out. Josh wrote something very early on in this forum: don't be afraid to bluff off your entire stack. He meant times like this.
