The .7 HEMI engine has become a popular choice among performance enthusiasts looking to maximize horsepower and torque. One of the most effective modifications to achieve this is a cam swap, particularly when paired with a quality stroker kit. In this article, we will explore how to achieve 500+ RWHP using Crane Cams and a stroker kit.
Understanding the .7 HEMI Engine
The .7 HEMI engine, known for its robust design and performance capabilities, offers a solid foundation for modifications. With its unique hemispherical combustion chamber, it allows for efficient airflow and combustion, making it an ideal candidate for high-performance upgrades.
Benefits of a Cam Swap
A cam swap can significantly enhance engine performance by altering the timing and duration of the valve openings. This change can lead to improved airflow, increased power output, and better throttle response. Here are some key benefits:
- Increased Horsepower: A performance cam can provide a noticeable boost in horsepower.
- Enhanced Torque: Improved torque delivery across the RPM range.
- Better Sound: A more aggressive cam profile often results in a more appealing engine sound.
Choosing the Right Crane Cam
Crane Cams offers a variety of camshafts specifically designed for the .7 HEMI engine. When selecting a cam, consider the following factors:
- Lift and Duration: Higher lift and longer duration can increase power but may require additional modifications.
- RPM Range: Choose a cam that matches your desired RPM range for optimal performance.
- Compatibility: Ensure the cam is compatible with your existing engine setup.
Integrating a Stroker Kit
A stroker kit increases the engine’s displacement, allowing for more air and fuel to enter the combustion chamber. This additional capacity complements the cam swap, further enhancing performance. Key advantages of a stroker kit include:
- Increased Displacement: More displacement translates to more power.
- Improved Torque: A stroker kit enhances low-end torque, making the vehicle more responsive.
- Better Performance: The combination of a stroker kit and a performance cam provides a significant performance increase.
Installation Process
Installing a cam and stroker kit requires careful attention to detail. Here’s a general overview of the installation process:
- Preparation: Gather all necessary tools and components before starting the installation.
- Remove the Engine Components: Take off the intake manifold, valve covers, and other components to access the camshaft.
- Replace the Camshaft: Remove the old cam and install the new Crane cam following the manufacturer’s instructions.
- Install the Stroker Kit: Follow the kit instructions to ensure proper installation of the new pistons and crankshaft.
- Reassemble the Engine: Carefully put everything back together, ensuring all gaskets and seals are replaced.
Tuning for Maximum Performance
After completing the installation, tuning the engine is crucial for achieving optimal performance. A proper tune will ensure that the air-fuel mixture is ideal for the new cam and stroker kit. Consider the following:
- ECU Tuning: Reprogram the engine control unit to accommodate the new modifications.
- Dyno Testing: Conduct a dyno test to measure the engine’s performance and make necessary adjustments.
- Fine-Tuning: Adjust timing and fuel maps for maximum efficiency and power output.
Conclusion
By swapping the cam and integrating a stroker kit, achieving over 500 RWHP with a .7 HEMI engine is entirely possible. With the right components from Crane Cams and careful installation and tuning, you can unlock the full potential of your engine. Embrace the power and performance that comes with these modifications, and enjoy the thrill of driving a truly high-performance vehicle.
