run at least some 38s on that set up 46 I would say would be better for you. Go ahead and upgrade them. If not you are going to run lean as **** on the top end. Better to do it right then to spend all that money for no reason. Im guessing you are on the stock fuel pump also.. You might get away with it for a while. Just make sure you have all the supporting mods.. would hate to see a new motor get trashed.
