Holley is pleased to announce the release of MSD Atomic Billet Fuel Rails for LS1/2/6, LS7, and LT1 engines. Developed specifically for MSD AirForce Manifolds, they're available in two versions – just the fuel rails themselves or in comprehensive kits with the rails, fuel fittings, O-ring fittings, mounting brackets, and all the hardware to plumb the system. MSD Atomic Billet Fuel Rails feature a black-anodized/bright-dip finish with laser-etched logos that'll look great for years and a 5/8-inch fuel passage with the flow capacity to fuel high-horsepower applications.

MSD Atomic Billet Fuel Rails are perfect for MSD Atomic AirForce Intake Manifolds, which just became available with a solid black or gray logo (in addition to the traditional red). They feature unique bell-mouthed runner entrances that maximize airflow and minimize shrouding, optimizing the available plenum volume for an unobstructed flow path over opposing runners. Atomic AirForce intakes have a huge 103mm throttle bore, a two-piece configuration that makes it easy to custom-pork the intake runners, and come complete with gaskets and all the hardware for a direct bolt-on installation.
