I would say to increase primary jet size, bore shooters and steeper rear gears would provide much stronger launch ...with rpm air gap a having small advantage
I have the primary jets for a 440 carb. Right now it's just some tuning that I have to do.
I'm sticking with the gears I have since I do primarily highway travel. Im totally fine with sacrificing a bit of launch. Sounds like its not really worth me switching intakes tho....
