Thanks for the technical data. I always want my builds to be as accurate as possible, if possible and this information helps for the future. After reading your response I went back and looked at the library of research photos of modern super stock hemi engines and noticed the slight offset on all the carb setups that I never saw before. And, since I have at least 10 more of these Darts and Cudas to build I will look into what Fireball offers for more accurate carbs. Thanks.
