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)

Leave it to MSD to build an all-out performance distributor to replace the OEM GM LT1 Optispark. We machine an entire billet block of aluminum down into a precise housing that fits in place of the factory piece. Then, we fill it with a reliable new pick-up assembly, a trick timing adjustment mechanism and top it off with an all new MSD distributor cap. The pick-up is an advanced optical encoder, a different style of optical pickup than the OEM. This type of pick-up has proven to be very reliable and stable through extreme rpm and conditions. The rotor is bolted to a drive assembly that is indexed to the shaft and is stabilized through the use of a large ball bearing assembly. Once installed, you have the ability to adjust the ignition timing. The only distributor that offers timing adjustability. An adjustment screw allows the timing to be tweaked up to 5 degrees. The distributor is equipped with a fresh air vent and has an extra thick mounting surface for the cap to eliminate leaks. The distributor is supplied complete with our heavy duty LT1 cap, rotor and the components required for installation.

Product Features:

• Advanced optical encoder trigger design for accuracy/reliability.
• Rotor drive design is positively indexed and cannot slip.
• Large ball bearing stabilizes timing through 10;000 rpm.
• Fresh air vented and sealed to keep the elements out.
• Improved housing design and extra bolt eliminates leaks
• Easily Adjust The Timing Up To +/-5 deg.
