Why did Ford change its 302 firing order?
Ford's decision to change the firing order of its iconic 302 cubic inch V8 engine was a strategic move to improve the engine's performance and efficiency. The 302 engine, also known as the "small block" Ford V8, was a popular choice for many Ford vehicles in the 1960s and 1970s. However, the original firing order of the engine was not optimized for maximum power and torque output.
The Original Firing Order
The original firing order of the Ford 302 engine was 1-5-4-2-6-3-7-8. This firing order was common for many V8 engines of the era, as it helped to balance the engine's vibrations and provide a smooth running experience. However, this firing order did not necessarily maximize the engine's power potential.
The Revised Firing Order
In the late 1960s, Ford engineers decided to revise the firing order of the 302 engine to 1-3-7-2-6-5-4-8. This new firing order provided several benefits:
- Improved power and torque output by optimizing the timing of the power strokes
- Reduced engine vibrations and improved overall smoothness
- Enhanced fuel efficiency by improving the engine's combustion efficiency
The revised firing order also helped to balance the engine's crankshaft forces, which in turn reduced wear and tear on the engine components. This resulted in a more durable and reliable engine that could withstand the demands of high-performance driving.
The Impact of the Firing Order Change
The change in firing order had a significant impact on the performance of the Ford 302 engine. Horsepower and torque output increased, allowing Ford to offer more powerful and responsive versions of its popular muscle cars and sports cars. The improved efficiency and durability of the engine also contributed to its long-lasting popularity and widespread use in a variety of Ford vehicles.
Overall, the decision to revise the firing order of the Ford 302 engine was a strategic move that paid dividends in terms of improved performance, efficiency, and reliability. This change helped to solidify the 302's reputation as a reliable and powerful engine that could meet the demands of both everyday driving and high-performance applications.
