The classic 1970 Dodge Challenger is an iconic muscle car that has captured the hearts of automotive enthusiasts for decades. With its powerful engine and aggressive styling, it represents the golden age of American performance vehicles. In this article, we will explore how a 1970 Challenger was transformed from a respectable 350 horsepower to an impressive 420 horsepower using Edelbrock and MSD components.
Understanding the Base Engine
The starting point for this transformation was a 1970 Challenger equipped with a 383 cubic inch V8 engine. This engine, while powerful, was limited by its factory components and tuning. The goal was to enhance its performance significantly without sacrificing reliability.
Choosing the Right Components
To achieve the desired horsepower increase, specific components were selected for their performance benefits. The two primary brands chosen for this upgrade were Edelbrock and MSD, known for their quality and effectiveness in the aftermarket performance industry.
Edelbrock Components
- Edelbrock Performer RPM Intake Manifold: This manifold is designed to improve airflow and increase power across the RPM range.
- Edelbrock Carburetor: A 750 CFM carburetor was chosen to provide the engine with the correct fuel mixture for optimal performance.
- Edelbrock Aluminum Cylinder Heads: These heads reduce weight and improve airflow, contributing to the overall horsepower increase.
MSD Components
- MSD Ignition System: An MSD ignition box was installed to provide a stronger spark, improving combustion efficiency.
- MSD Distributor: This distributor ensures precise timing, which is crucial for maximizing power output.
- MSD Spark Plug Wires: High-performance wires were used to ensure the spark reaches the plugs without loss.
Installation Process
The installation of these components required careful planning and execution. The following steps outline the process:
- Removing the Old Components: The factory intake manifold, carburetor, and ignition system were removed to make way for the new parts.
- Installing the Edelbrock Intake and Carburetor: The new intake manifold was bolted on, followed by the carburetor, ensuring all gaskets were properly seated.
- Upgrading the Cylinder Heads: The old heads were replaced with Edelbrock aluminum heads for improved airflow and efficiency.
- Setting Up the MSD Ignition: The MSD ignition box and distributor were installed, with careful attention to timing settings.
Tuning for Performance
Once the components were installed, tuning was essential to maximize performance. A professional tuner was brought in to adjust the carburetor settings and ignition timing. This step ensured that the engine was running at its best, taking full advantage of the new parts.
Results and Performance Gains
After the installation and tuning, the results were impressive. The engine was dyno-tested, revealing a jump in horsepower from 350 to 420. This significant increase not only enhanced the driving experience but also showcased the effectiveness of the Edelbrock and MSD components.
Conclusion
The journey of upgrading a 1970 Challenger from 350 to 420 horsepower demonstrates the potential of aftermarket components in enhancing classic muscle cars. With the right parts and professional installation, enthusiasts can unlock the true performance capabilities of their vehicles. Whether for street use or track days, the combination of Edelbrock and MSD has proven to be a winning formula.
