Ready-to-Run Nailhead Pro-Billet Distributor
The Buick Nailhead is one of the most sought after nostalgic engines for rods and is still providing the smooth power to plenty of pre-muscle car era Buick’s. Nailhead fans can finally get a state-of-the-art distributor to provide the fire!
MSD’s new 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. The weights slide on nylon bushings for smooth timing changes and the entire assembly is QPQ coated for friction reduction and corrosion resistance. MSD supplies different advance springs and stop bushings so you can tune a timing curve to match your Nailhead’s needs!
MSD uses a sealed ball bearing to support a polished steel shaft to provide endurance and stability. A precision reluctor is mounted to this shaft and is responsible for triggering the magnetic pickup – which never needs adjustment! 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 up your Nailhead!
