1989 Mercury Grand Marquis Performance Distributors

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’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.
