1984 Ford Thunderbird Performance Distributors

Fits Ford 289 – 302 (5.0). Utilizing the durable and dependable High Energy Ignition (HEI) system pioneered by GM, these distributors avoid the unsightly wiring of stock Ford electronic ignition systems by installing this one-piece distributor with an internally positioned coil and module. Easy to install: just connect one 12-volt hot wire to the distributor (has optional tach hook-up). These units offer calibrated advance curves that are optimized for maximum combustion efficiency and for the elimination of detonation damage and throttle ping. Assembled from precision-madeparts for advance curve smoothness. Offers longer term durability and a higher voltage spark that permits a bigger spark plug gap, resulting in more power and reduced plug fouling. Each unit includes a high-power coil, a premium hi-dielectric cap with brass terminals, and a low-saturation ignition module. By eliminating the stock-Ford ballast resistor, more ignition voltage results in improved spark. Incorporates easily found High Energy Ignition (HEI) replacement parts. Assembled with upper and lower bushings (stock Ford distributors have only a single bushing). Technical Note: Gear not compatible with roller cams. If using roller cams, please contact the cam manufacturer for proper gear selection.

• Features Red Cap
• Fits Ford 289-302 5.0 Engines

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:

• Equipped w/Steel Gear
• CARB E.O. Approved
• Does not require an MSD Ignition Control
• Supplied w/small dia. cap w/HEI style terminals; race and rotor
• Will accept PN[8441] Cap-A-Dapt
• Nylon pads ensure smooth operation of the advance weights
• Advance weight pins are staked and tig welded to the plate
• Mech. advance assem. can be locked out for crank trigger systems

For Ford enthusiasts that are serious about performance! Just under the brass terminals of the MSD cap and rotor is an easy-to-adjust mechanical advance assembly. The assembly is fine blanked from chromoly steel, rig-welded for strength plus receives a QPQ coating. The precision weights glide on nylon bushings for smooth advancement and different springs and stop bushings are supplied so a variety of advance curves can be tuned. The steel shaft that spins the advance and reluctor receives a friction reducing coating plus is guided by a sealed ball bearing and long sintered bushing. This combination provides stable timing signals and spark delivery at any RPM. Triggering chores are handled by MSD’s race proven, maintenance-free magnetic pick-up.

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.
