1961 Buick Invicta Performance Distributors

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.
