A King Demon RS series carburetor (PN 9838020DR) completes the installation. The King Demon features removable venture sleeves in order to make it work in any condition, or on different engines. Matt uses the 1195cfm sleeves for this application (this RS series carb allows for ratings from 1095 to 1495cfm, depending on the engine's requirements). Annular boosters pull more fuel, which will produce more torque at lower rpm by creating more signal, while also reducing area inventory inside the venturi. Overall, Matt says the Demon has the best fit-and-finish casting he's ever seen, as well as providing him nearly infinite tuning possibilities. As for that manifold, many think you need to use a custom sheetmetal version, but Dart has a cost-effective, bolt-on cast version available, and it's in use here.
