1991 Ford F Super Duty Performance Distributors

All the quality and performance you’ve come to expect from MSD is now available in black. Our customers have requested black parts for their builds so we’ve answered with the addition of several black distributor caps and cap and rotor kits. The black parts are built to the exact specifications of the traditional MSD red components. If you’re looking to change up the look under the hood of your street machine, off-road rig or race car; check out the complete line of MSD black components.

Product Features:

• Injection Molded From DuPont Rynite Material
• Extreme strength; high dielectric properties
• Designed with performance in mind
• High quality; voltage insulating material
• Brass terminals
• Black in color

The cap and rotor of any ignition system must be considered maintenance items. Just as you change the oil and filter of your car, you should always replace the cap and rotor as a set. To make things easy, we now offer these cap and rotor replacement kits.

Product Features:

• Injection Molded Housing From Dupont Material
• Extreme Strength; High Dielectric Properties
• Designed w/Performance In Mind
• High Quality; Voltage Insulating Material
• Stainless Steel Rotor Tip Design
• Resist Carbon Tracking
• Max Voltage Transfer

MSD Pro-Billet Distributors are the finest performance and racing distributors available. Every feature has been engineered to endure the rigors of high performance and racing engines. Whether cruising the streets or racing stock cars, dragsters, boats or trucks, MSD has a distributor for it. MSD uses state-of-the-art, Computer Numerical Controlled (CNC) mills and lathes to machine each housing. After a long series of precise cuts and movements, the billet is formed into a flawless distributor housing that is accurate to within 0.001″. The flex-free housings are lightweight, have no porosity or weak areas and look great on polished, show quality engines.

Product Features:

• CNC machined billet aluminum housing and Dupont Rynite base
• No CARB Exemption Order Number
• Supplied w/Cap-A-Dapt and rotor (accepts MSD socket style caps)
• Must Be Used w/An MSD Ignition Control
• Mech. advance assem. can be locked out for crank trigger systems
• Nylon pads ensure smooth operation of the advance weights
• Advance weight pins are staked and tig welded to the plate
• 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

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:

• Advance weight pins are staked and tig welded to the plate
• Nylon pads ensure smooth operation of the advance weights
• Supplied w/small dia. cap w/HEI style terminals; race and rotor
• Will accept PN[8441] Cap-A-Dapt
• Does not require an MSD Ignition Control
• CARB E.O. Approved
• Now includes built-in Rev Limiter
• 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
• Equipped w/Steel Gear
• Simple And Clean Installation w/Only Three Wires To Connect

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 In. 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. Note: must be used with an MSD 6, 7 or 8-series ignition.
