You will essentially never make him fold a better hand, so any further aggression on your part is very likely a mistake. The size of the board makes the credibility of a flop 3-bet near zero. In my opinion the best line is to use your gutshot as an escort to the river and then make your decision of whether to call or fold based on your assessment of his likelihood to both have a busted draw and fire three barrels with it given the turn and river cards.
