Dart BBC 4150 Flange Intake Manifold (9.8 Deck) These single-plane, air-gap style manifolds have a raised water crossover to insulate incoming air, optimized intake-runner cross sections to maintain high mixture velocity, and extended runner dividers to equalize port lengths. Dart also incorporated integral nitrous bosses on these manifolds, for those wanting even more power.
