What Does VIN Mean for the 1970 Cougar?
The VIN, or Vehicle Identification Number, is a unique code assigned to every car. It tells you important information about the vehicle, including the year, make, model, and engine type. For the 1970 Mercury Cougar, the VIN includes an engine code, which helps to identify the type of engine under the hood. This is where the “70 Cougar VIN M vs H” comes into play, distinguishing between two specific engine types available for the Cougar that year.
The 70 Cougar VIN M: The Performance-Oriented Choice
The M code in the VIN of a 1970 Mercury Cougar refers to the 351 cubic inch, 4-barrel Cleveland V8 engine. This engine was designed with performance in mind, offering more power and a higher top speed than the H code engine. The M code engine produced around 300 horsepower, which was quite impressive for the time.
If you’re looking for a 1970 Cougar with more muscle, the M code is the way to go. This engine was paired with a 4-barrel carburetor, allowing it to draw more fuel and air into the engine for better combustion and greater overall performance. As a result, M code Cougars were often favored by enthusiasts who wanted a car that could compete with other muscle cars of the era, such as the Ford Mustang or Chevrolet Camaro.

Displacement
Both the M code and H code engines in the 1970 Mercury Cougar share the same displacement of 351 cubic inches (5.8 liters). This means that both engines have the same overall size in terms of how much air and fuel they can combust. However, despite having the same displacement, these engines perform quite differently due to other design factors, such as the carburetor and engine block design.
Carburetor
One of the key differences between the 70 Cougar VIN M vs H engines is the type of carburetor used. The M code engine features a 4-barrel carburetor, which allows more air and fuel into the engine, resulting in greater combustion and more power. On the other hand, the H code engine uses a 2-barrel carburetor, which restricts the airflow and fuel slightly, making it a more fuel-efficient option but with less raw power.
Horsepower
The most notable distinction between the M code and H code engines is their horsepower. The M code engine produces 300 horsepower, making it the high-performance option. This extra horsepower translates to faster acceleration and higher top speeds, ideal for muscle car enthusiasts. In contrast, the H code engine produces 250 horsepower, which is still respectable but geared more toward everyday driving rather than high-speed performance.
Torque
Torque is another important factor when comparing the 70 Cougar VIN M vs H engines. The M code engine delivers approximately 385 lb-ft of torque, which provides a greater thrust when the car accelerates from a stop. Meanwhile, the H code engine produces around 355 lb-ft of torque, offering decent pulling power but not quite matching the aggressive feel of the M code.
Performance Focus
The M code engine was built with performance in mind, making it the choice for those who wanted a true muscle car experience. With its high horsepower and torque, the M code was designed for speed and high-performance driving, suitable for racing and car enthusiasts who craved power. On the other hand, the H code engine was designed for a more balanced performance, providing enough power for daily driving but without the focus on high-speed thrills.
Fuel Efficiency
Fuel efficiency is an area where the H code engine has an advantage over the M code. The M code engine’s 4-barrel carburetor allows for more fuel consumption, which, while boosting performance, reduces fuel efficiency. In contrast, the H code engine with its 2-barrel carburetor is more fuel-efficient, making it a better option for those concerned with fuel consumption, especially if the car was going to be driven regularly.
Collector Value
For classic car collectors, the M code Cougar tends to have a higher value due to its rarity and enhanced performance. Muscle car enthusiasts often seek out the M code because of its association with power and speed, making it a prized possession. The H code Cougar, while still valued for its practicality, generally does not command as high a price as the M code due to its more common configuration and lower performance specs.
Rarity
In terms of rarity, the M code engine is less common than the H code. This is primarily because fewer M code Cougars were produced, making them harder to find today. As a result, the M code is often more sought after by collectors who want something unique and rare. The H code engine, being more widely produced, is easier to come by, although still valuable as part of the 1970 Cougar lineup.
Purpose
The primary purpose of the M code engine was to offer a high-performance option for drivers who wanted a muscle car with serious power. This engine was ideal for enthusiasts who enjoyed racing or simply wanted a car that could outperform most others on the road. On the other hand, the H code engine was built for practicality. It offered enough power for regular driving without the extra cost and fuel consumption associated with high-performance engines.
Engine Block Design
Another difference between the M code and H code engines is the design of the engine block. The M code used the Cleveland engine block, which was designed for high RPMs and greater performance. The Cleveland block was known for its large valves and high-flow heads, which contributed to its superior power. The H code used the Windsor engine block, which was more versatile and efficient, designed for durability and everyday use rather than maximum performance.
Primary Use Case
The M code engine was primarily used for racing and high-speed performance. It was the engine of choice for drivers who wanted to push their 1970 Cougar to its limits, whether on the street or the track. The H code, on the other hand, was more suited for general driving. It provided a good balance of power and fuel efficiency, making it ideal for those who wanted a reliable and stylish car without the need for extreme performance.
Popularity
Among muscle car collectors and enthusiasts, the M code engine is more popular due to its performance capabilities and rarity. Many car enthusiasts are drawn to the raw power and excitement that the M code engine provides, making it a favorite for those who appreciate muscle cars. The H code, while not as popular in performance circles, is still appreciated by drivers who want a balanced car that offers both power and fuel efficiency.

The 70 Cougar VIN H: The Standard V8 Option
On the other side of the “70 Cougar VIN M vs H” debate is the H code engine. The H code refers to the 351 cubic inch, 2-barrel Windsor V8 engine. While this engine is still a V8, offering plenty of power by modern standards, it was not as performance-focused as the M code engine. The H code engine produced around 250 horsepower, making it a more practical and affordable option for everyday driving.
The H code engine featured a 2-barrel carburetor, which restricted the amount of fuel and air entering the engine compared to the M code’s 4-barrel setup. This made the H code Cougar a more fuel-efficient choice, especially during an era when fuel economy was starting to become a consideration for drivers.
Which Should You Choose?
When deciding between the “70 Cougar VIN M vs H”, it ultimately comes down to what you’re looking for in a car. If you value performance and want a car that can deliver raw power, the M code is the better option. With its 300 horsepower engine and 4-barrel carburetor, the M code Cougar is built for speed and performance, making it a favorite among muscle car enthusiasts.
On the other hand, if you’re looking for a 1970 Cougar that offers a balance between power and practicality, the H code engine might be more appealing. While it doesn’t offer the same level of performance as the M code, the H code is still a V8 engine with plenty of power for most driving situations. Plus, its 2-barrel carburetor makes it a more fuel-efficient option, which could be important if you plan to drive the car regularly.
