I'd b/f $385. Yes you're not going to get looked up by alot worse but you definitely have to bet, not just because he can have worse 10x as well as look you up with random crap on occasion but you need to balance for the times you're just following through with a bluff. Any smaller you're likely to induce bluff jams and any bigger I think is bad due to an smaller likelyhood of worse hands looking you up. I'd also go slightly bigger on the turn, like $184.
