Mercury Grand Marquis 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.

• Street/Strip Version
• Built-In Coil with Magnetic Trigger
• Features Red Cap
• Fits Ford 289-302 5.0 Engines

When you start making serious power with your EFI Ford, the stock distributor shaft is one of the weak links of the engine. These Pro-Billet models answer the need for an affordable replacement in a strong and great looking package. Each distributor starts as a solid billet that is secured into a state-of-the art computer numerical control (CNC) machine where it is transformed into a precision housing. Inside each housing there is a sealed ball bearing at the top of the shaft. This design is responsible for accurately guiding the oversized polished steel shaft throughout the entire RPM range of your engine. The shaft is also quip-coated for friction reduction and corrosion resistance. The Pro-Billet distributors use a stock-style trigger pick-up to accept factory connectors. For installation, you simply remove the stock distributor and bolt the Pro-Billet MSD in. Place! Each model is supplied with a high-quality cap with brass terminals for full spark delivery, heavy-duty rotor.

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

MSD is excited to offer two Ready-to-Run distributors for two classic Ford engines! These distributors are the answer to weak breaker points or rebuilt aftermarket models. Inside the billet housing there is a high-output ignition module. When the maintenance-free magnetic pick-up signals the module to fire, up to 7.5 A is sent to the coil where a powerful spark is created. This improved spark output results in quick starts, snappy throttle response and terrific drivability. The distributors are equipped with a vacuum advance canister for cruising economy. Plus, there is a mechanical advance assembly that is mounted on top of the distributor shaft making it easy to adjust the advance to meet your needs. Another great feature of the Ready-to-Run distributors is their simple installation! All you need to do is connect three wires and you’ll be cruising!

Product Features:

• Simple and clean three wire installation
• 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

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.

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.
