The distributor cap & rotor are just two pieces of this type of ignition system which is typically driven by the engine’s camshaft. The distributor is the device that delivers the ignition spark to the spark plugs at a precise time, and spark timing is critical. Any wear or component out of place in this type of system will result in failure. Within the distributor and mounted to it are many individual pieces which allow the distributor and system to be maintained and repaired to keep it in top working order.

Product Features:

• All products are constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.
• Cap terminal conductor wires formed with precision guided machines to ensure precise final location in the final housing assembly.
• Terminal inserts manufactured to precise tolerances to ensure a guaranteed electrical connection between the cap conductor wires and spark plug wire terminals.
• Distributor rotor blade coated with RFI coating to prevent electrical magnetic interference with the vehicles electrical system.
• Distributor and rotor housings manufactured using the latest plastic technologies to guarantee di-electric strength and long life cycle.

Our line of Billet Plug n¿ Play Distributors are based on a precision CNC-machined housing with an upper ball bearing to support the steel distributor shaft accurately from idle to redline rpm. These distributors feature our maintenance-free Ignitor II or III electronic ignition module to produce a strong spark and steady ignition timing.

Product Features:

• Plug n’ Play billet distributors are designed for maximum ignition performance at a price you can afford
• Our Billet I3 distributors ship with Ignitor III multi-spark rev limiting modules.
• Precision CNC machined 6061-T6 billet aluminum housings are lightweight yet offer maximum strength.
• Each billet distributor is hand polished and buffed to a high luster Tempered distributor shaft has low torsion displacement for accurate timing and extended operational life.
• Adjustable mechanical advance with proprietary limiting function permits multiple settings. Distributors are factory set with a performance advance curve and are provided with additional springs for custom advance.

The Buick Nailhead is one of the most sought after nostalgic engines for rods and is still providing the smooth power to plenty of Buick’s. Nailhead fans can finally get a state-of-the-art distributor to provide the fire! MSD’s Nailhead distributor is a ready to run unit which incorporates a magnetic pickup that never wears out. Plus, the distributor has a built in ignition module so there is no need to mount an external MSD Ignition control. The module delivers up to 7.5 A to the coil creating a stout inductive spark. Not only do you get the benefits of electronic triggering, but your engine will awaken with powerful sparks from the ignition module. This improves combustion of the fuel mixture resulting in quick starts, a smooth idle and great performance.

Product Features:

• Simple and clean three wire installation
• Includes built-in Rev Limiter
• Does not require an MSD Ignition Control
• Supplied w/HEI style distributor cap/rotor (accepts Cap-A-Dapts)
• Mech. advance assem. can be locked out for crank trigger systems
• Advance plate and weights are fine blanked from chrome moly steel
• QPQ coated for friction reduction
• QPQ coated polished steel shaft; guided by sealed ball bearings
• Maintenance-free magnetic pickup and precision reluctor
• Creates stable trigger signals throughout the rpm range
• CNC machined billet aluminum housing and billet aluminum base
• Vacuum advance canister for improved economy (can be locked out)
