I think calling the turn is the worst option, given the stack sizes, opponent might give up on the river with his bluffs on a blank,you'll have 350 left, pot 930, and nearly any scare card will hit he's range.
I'd prefer folding the turn, he still has quite a few flushes, KK+, and even if he bets AK, AQ with a spade and AJs you don't have enough equity there.
Your range looks strong given the action, and if opponent is good, it's unlikely he'll bet the turn with AK-AQ no spade, or a random bluff
