Review FORD Mercury 2bbl. Carburetor 1981 87 5.8l Inch Eng..o.t Full Size fits 351 1981-87

Introducing the Ford 5587-R Mercury 2-barrel carburetor, specifically designed for 1981 to 1987 Ford and Mercury vehicles equipped with the 5.8L 351 Windsor engine and automatic overdrive transmission (AOD). This carburetor is a critical component of your engine's fuel delivery system, ensuring optimal performance, fuel efficiency, and drivability.

The Ford 5587-R Mercury carburetor is a 2-barrel unit, meaning it has two throttle barrels. Each barrel is responsible for managing the fuel flow to one side of the engine. The barrels are topped with mechanical secondaries, which provide additional fuel for high RPM operation, enhancing engine power and performance.

This carburetor utilizes a vacuum secondary system. When engine vacuum increases, the secondary diaphragms open, allowing more fuel to enter the secondary throats. This results in a more powerful fuel/air mixture for better performance, particularly during acceleration.

The 5587-R Mercury carburetor features an electric choke system. With this setup, the choke plate is engaged by an electric solenoid when the ignition switch is turned to the "start" position. Once the engine reaches operating temperature, the solenoid disengages, and the choke plate retracts, allowing for normal fuel delivery.

A key feature of this carburetor is its adjustability. It comes with adjustable primary and secondary idle mixtures, enabling you to fine-tune the idle speed and quality for your specific engine application. Additionally, you can adjust the idle mixture screws to optimize fuel economy and reduce emissions.

The base of the carburetor includes a fuel pressure regulator. This component maintains a consistent fuel pressure in the fuel system, ensuring proper carburetor performance and preventing fuel starvation during high engine load conditions.

The Ford 5587-R Mercury 2-barrel carburetor is an essential component for maintaining the performance and drivability of your 1981 to 1987 Ford or Mercury vehicle with a 5.8L 351 Windsor engine and automatic overdrive transmission. With its mechanical secondaries, vacuum secondary system, electric choke, adjustability, and fuel pressure regulator, this carburetor provides the reliable and efficient fuel delivery your engine needs.

The Ford 5587-R Mercury 2-barrel carburetor was used in Ford and Mercury vehicles with the 5.8L 351 A.O.T (Automatic Overhead Valve) engine from 1981 to 1987. Here are some pros and cons of buying this carburetor for your vehicle.

1. Availability: These carburetors are widely available on the aftermarket, making them relatively easy to find and purchase.

2. Fitment: They are specifically designed for the 5.8L 351 A.O.T engine, ensuring a perfect fit.

3. Cost-effective: Compared to newer electronic fuel injection systems, carburetors are generally less expensive to purchase and install.

4. Better control: Carburetors offer better control over engine performance, allowing for easier adjustment of the fuel-air mixture to optimize engine response and power output.

1. Fuel efficiency: Carburetors are less fuel-efficient than newer fuel injection systems, as they tend to deliver more fuel than necessary, especially during cruising speeds.

2. Maintenance: Carburetors require more frequent maintenance than fuel injection systems. They have more moving parts, which can wear out over time and require replacement.

3. Emissions: Carburetors produce more emissions than fuel injection systems, which can be a concern for those looking to maintain a clean exhaust system.

4. Cold starting: Carburetors can be more difficult to start in cold weather conditions, as the fuel-air mixture can be harder to ignite.

The Ford 5587-R Mercury 2-barrel carburetor is a viable option for those looking to replace the original carburetor on their 1981-1987 Ford or Mercury vehicle with a 5.8L 351 A.O.T engine. While they offer good fitment, ease of availability, and better control over engine performance, they also come with some drawbacks, including higher maintenance requirements, lower fuel efficiency, and higher emissions.

If you are looking for a cost-effective solution and prefer the feel and sound of a carbureted engine, then the Ford 5587-R Mercury 2-barrel carburetor is a good choice. However, if you prioritize fuel efficiency, ease of maintenance, and reduced emissions, it may be worth considering upgrading to a more modern fuel injection system. Ultimately, the decision comes down to personal preference and priorities.
