MSD Ford 351W Small Diameter Pro-Billet Distributor - 8578
MSD Ford 351W Small Diameter Pro-Billet Distributor - 8578 - Image 2 MSD Ford 351W Small Diameter Pro-Billet Distributor - 8578 - Image 2
MSD engineers fit all of their high performance distributor experience into a special compact housing designed to be less obtrusive for Ford engines. The diameter of the special cap and housing are 5/8" smaller than stock Ford distributors providing extra room in front of the engine. The new MSD cap features spark plug style terminals and is firmly screwed down to the housing.

The distributor relies on MSD's race proven magnetic pickup and precision reluctor to deliver accurate trigger signals to the MSD Ignition throughout high rpm. The reluctor assembly is turned by a hardened steel shaft which rides in a sealed ball bearing for high rpm stability and endurance.

Mounted to the top of this shaft is a fully adjustable mechanical advance assembly. The rate at which the chromoly assembly advances the timing is easily controlled by changing the supplied advance springs and stop bushing for total advance.

  • Billet housing is 5/8” smaller in diameter than stock Ford distributors

Who is MSD Ignition?

MSD Ignition started back in 1970. Based in El Paso Texas, the company is known for creating quality ignition systems for various automobiles. Today, they are considered the leading company when it comes to the ignition system and has become a brand recognized all over the world.

Changing the Way Vehicles are Made

MSD has helped shape the automotive industry by being the first company in the world to conduct an experiment regarding Multiple Spark Discharge for a vehicle’s ignition system. It has been suggested by Engineers who were working on the White Sands Missile Range in Southern Mexico. They noticed that their quest for power is limited by the amount of spark the ignition system can only generate. Hence, the idea of Multi Spark Discharge.

Racing Application

Soon after the product introduction, racers started applying it to their race cars. Due to its success, other top teams started using MSD which helped paved the way for the brand’s popularity. The majority of the race engines today use MSD and have proven to produce race champions.

The company operates in a 100,000 square feet facility in Texas. They house some of the most state-of-the-art equipment that helps them create products that are superior in quality.
