Ford 351W Windsor 8400 Series Pro Billet Distributor [Red]

Pro Billet Distributors are designed for enthusiasts that are serious about performance. Speedmaster 8400 Series distributors feature CNC machined from Billet 6061-T6 Aluminum to give them precision tolerances, high strength and incredible endurance. The Billet Distributors are equipped with a large cap that has "spark plug" style terminals for secure wire attachment and maximum protection against crossfire. Extremely accurate magnetic pickup which never requires adjustment followed by an easy-to-adjust mechanical advance assembly. Precision weights glide on nylon bushings for smooth advancement and different springs are available so a variety of advance curves can be tuned. The 0.500 in. steel shaft that spins the advance and reluctor is guided by a sealed ball bearing and long sintered bushing. This combination provides stable timing signals and spark delivery at any RPM. These are mainly used in high performance and racing vehicles.

Billet Housing:
Speedmaster Magneto Series feture a distributor housing machined from billet aluminum. Speedmaster uses Computerised Numerical Controlled (CNC) mills and lathes to create each housing. This procedure produces a flawless, lightweight distributor housing that is accurate to within 0.001''.

Shaft and Ball Bearing Guide:
The complete line of Speedmaster Distributors uses a polished steel shaft that receives a QPQ, or Tuftride coating. This process produces a durable finish that reduces friction and resists corrosion. To accurately guide this shaft, Speedmaster uses a sealed ball bearing located at the top of the housing. At the bottom of the housing, an extra long sintered bushing controls the shaft. This combination keeps the shaft spinning smooth and accurately throughout 10,000+ rpm.

Magnetic Pickup:
These Speedmaster distributors use a high output magnetic pickup to trigger the ignition system. This pickup is completely maintenance free requiring no adjustment ever. The pickup is mounted to the base of the distributor housing and plugs directly into your Ignition Control. A trigger signal is created as a precision made reluctor (attached to the shaft) passes by. The reluctor has a ''paddle'' for each cylinder and when the paddle passes the pickup, a signal is created.

Adjustable Mechanical Advance:
One of the most important features of the Speedmaster distributors is the adjustable mechanical advance assembly. The advance assembly allows you to accurately modify the advance curve to match your specific application. To start with, the advance plate is stamped and machined from chrome moly, weight pins are then staked in and tig welded in place. This assembly, along with the weights, then receive a corrosion resistant QPQ coating.
