The Buick Nailhead is one of the most sought after nostalgic engines for rods and is still providing the smooth power to plenty of Buicks. Nailhead fans can finally get a state-of-the-art distributor to provide the fire! MSD’s Nailhead Distributor is a Ready-to-Run design which means that it doesn’t require an external ignition box. This is because inside the billet alumi­num housing there is a powerful ignition module capable of producing a high-output spark. This design also makes installation an easy affair with only three wires to connect! Just under the custom MSD cap and retainer is an accurate mechanical ad­vance assembly. MSD supplies different advance springs and stop bushings so you can tune a timing curve to match your Nailhead’s needs! A sealed ball bearing supports a polished steel shaft to provide endurance and stability. To top it off there is a vacuum advance canister which can help economy on long drives.The Ready-to-Run Distributor is supplied with everything you need to drop it in and fire!
