Talk to Dave Dudek, he runs the FAST 9 second Road Runner with a stock dual 4 inline setup. Too bad you already bought the EB setup, unless the wife's Hemi Cuda has a custom Air cleaner base those carbs won't work, the top openings are too big. If you ever decide to go with clone Street Hemi carbs for that setup (which use the same EB bases and provide just as much fuel) I can help you.
