Wow I had the same exact combination . But I had hyperutectic pistons . Any way my car ran 11.30’s and weighed 3500 , so honestly I think your running pretty well for what you have . I would have no problem spraying that combo . It won’t take 150 either . All your going to need is a .052 nitrous jet and I can almost guarantee your going to drop a second or more like nothing .
