Mercury Cyclone Performance Distributors

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 inch 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 pick-up 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.

Product Features:

MSD’s Ready-to-Run Ford distributors are the perfect upgrade for bulky Duraspark systems or ancient breaker point models. All you need to do is drop it in the engine, connect three wires and fire the engine. Each distributor features an ignition module that produces a powerful inductive spark to improve combustion of the fuel mixture resulting in quick starts, smooth idle and increased performance. The billet aluminum housings of these distributors are 5/8 In. smaller in diameter to accommodate induction setups and tight engine compartments. A maintenance-free magnetic pick-up is responsible for triggering the high voltage sparks while a sealed ball bearing guides an oversized shaft. Beneath the bolt down cap and MSD race rotor you’ll find MSD’s accurate mechanical advance assembly. Different advance springs and stop bushings are supplied so you can easily tune a curve to match your needs. Plus, there is a vacuum advance canister to increase economy on long drives.

Product Features:

• Simple And Clean Installation w/Only Three Wires To Connect
• Built-in module produces a 7.5 amp single spark through high rpm
• Easy-to-adjust mech. advance w/supplied springs and stop bushings
• Vacuum advance canister for improved economy (can be locked out)
• CNC machined billet aluminum housing and billet aluminum base
• Housing Is 5/8 in. Smaller In Diameter Than Stock Ford Distr.
• Maintenance-free magnetic pickup and precision reluctor
• Polished steel shaft is guided by a sealed ball bearing

The street pro-billet distributors are the perfect choice for powerful engines that see plenty of street time. The street models share the same features as the small diameter models shown above, plus feature a vacuum advance. This canister provides improved economy and an accurate mechanical advance lets you dial-in an advance curve to match your driving needs. A magnetic pick-up produces accurate trigger signals that remain stable throughout the entire rpm range of your engine and is completely maintenance-free.

Product Features:

• Billet housing 5/8 in. smaller dia. than stock Ford distributors
• CARB E.O. Approved
• Easy-to-adjust mech. advance w/supplied springs and stop bushings
• Vacuum advance canister for improved economy (can be locked out)
• CNC machined billet aluminum housing and billet aluminum base
• Maintenance-free magnetic pickup and precision reluctor
• Creates stable trigger signals throughout the rpm range
• QPQ coated polished steel shaft; guided by sealed ball bearings
• Advance plate and weights are fine blanked from chrome moly steel
• QPQ coated for friction reduction
• Mech. advance assem. can be locked out for crank trigger systems
• Advance weight pins are staked and tig welded to the plate

A distributor’s performance is only as good as its drive gear. MSD ignition has put a great deal of effort into researching and testing a variety of metallurgical compositions, heat treating and coatings to provide you with a durable, accurate and strong distributor gear. The result is a special iron alloy gear that is treated to a low-friction coating process. To you this means long life, an easy break-in period and reliable performance. Features micro polished surface for smooth contact. Proprietary formulated ductile iron. Melonite QPQ coated reduces friction and initial wear. Interstitial carbide concentration improves wear resistance and running properties.

Product Features:

• Increased outer hardened layer thickness (RC 55-60)
• Micro Polished Surface For Smooth Contact
• Proprietary formulated ductile iron.
• Melonite QPQ coated reduces friction and initial wear
• Interstitial carbide improves wear resistance/running properties

Mallory distributor gears are precision machined from alloy steel in our factory to exact original equipment specs. For use with cast flat tappet hydraulic/mechanical cams and austempered ductile iron roller cams.
