I am running a 383 with 915 Closed Chamber heads 2.14 intake valves 1.74 exh, .509 lift cam, standard rockers right now (need 1.6 rollers), Team G intake, Demon 850 carb, and MSD Ignition system in my 74 duster. Its pretty peppy. I had fenderwel headers that I recently sold, and have not decided what I am going to do for headers yet. I want 2" TTI's but dont want to cut a 800 dollar pair of headers.
