YMTC on a possible angle shooter

[Ratman138]

2/5 NL. I am playing well and have run my stack to ~1800. Villian is only one to have me covered with ~2200. I have him pegged as a semi decent player. He has run well, but has some skills to back him up.
I believe the pre-river action are irrelevant. I end up with the nut quads. I lead out a bet of $60 and he raises to $150. I verbally announce "raise" and havent touched my chips. he now declares, "I'm all in."
What do you do? Do I make a min raise hoping he really does go all? He may be shooting an angle and only wants me to raise the minimum so he can call and see my cards. Do I make a normal raise or do I push all in?
