When it comes to enhancing the performance of your Chevy 396, the right combination of components can lead to significant horsepower gains. One of the most effective setups includes the Comp Cams 12-403-8 Solid Lift Cam and the Edelbrock Performer RPM Intake. This article will guide you through the steps to achieve over 100 horsepower with these components.
Understanding the Components
Before diving into the installation process, it’s essential to understand the roles of the Comp Cams 12-403-8 Solid Lift Cam and the Edelbrock Performer RPM Intake in your engine’s performance.
- Comp Cams 12-403-8 Solid Lift Cam: This camshaft is designed to provide higher lift and duration, allowing for better airflow and increased power at higher RPMs.
- Edelbrock Performer RPM Intake: This intake manifold is engineered for maximum performance in the mid to high RPM range, optimizing airflow to the engine.
Preparation for Installation
Proper preparation is crucial for a successful installation. Here are the steps you should follow:
- Gather Tools and Materials: Ensure you have all necessary tools, including wrenches, sockets, and screwdrivers, as well as the camshaft and intake manifold.
- Engine Condition: Check the overall condition of your Chevy 396 engine. It’s ideal to perform a compression test to ensure the engine is in good health.
- Clean Work Area: Set up a clean and organized workspace to avoid losing small parts and to keep the installation process efficient.
Installation Steps
Removing the Old Components
Start by removing the existing intake manifold and camshaft. Follow these steps:
- Disconnect the battery to prevent any electrical issues.
- Remove the intake manifold bolts and carefully lift the intake off the engine.
- Remove the valve covers to access the camshaft.
- Take off the timing chain cover and remove the timing chain.
- Unbolt the old camshaft and carefully extract it from the engine.
Installing the Comp Cams 12-403-8 Solid Lift Cam
With the old camshaft removed, it’s time to install the new Comp Cams 12-403-8 Solid Lift Cam:
- Lubricate the new camshaft with assembly lube to prevent damage during initial startup.
- Carefully slide the camshaft into place, ensuring it aligns with the timing gears.
- Reinstall the timing chain and cover, securing it with the appropriate bolts.
- Replace the valve covers, ensuring a proper seal to avoid leaks.
Installing the Edelbrock Performer RPM Intake
After the camshaft is in place, proceed with the installation of the Edelbrock Performer RPM Intake:
- Clean the surface of the engine where the intake manifold will sit to ensure a good seal.
- Apply a thin layer of gasket maker to the intake gaskets, then place them on the engine.
- Carefully position the intake manifold over the gaskets and lower it into place.
- Secure the intake with the provided bolts, tightening them in a crisscross pattern to ensure even pressure.
Tuning the Engine
After installation, tuning your engine is essential to maximize the performance gains from the new camshaft and intake. Follow these steps:
- Adjust the Timing: Set the ignition timing according to the specifications provided by the camshaft manufacturer.
- Fuel Mixture: Ensure your carburetor is tuned to provide the correct air-fuel mixture for optimal performance.
- Check for Leaks: Inspect all connections for any signs of leaks, especially around the intake manifold.
Testing Your Results
Once everything is installed and tuned, it’s time to test your engine:
- Start the engine and let it idle, listening for any unusual noises.
- Take the car for a test drive, paying attention to the throttle response and overall performance.
- Consider using a dynamometer to measure your horsepower gains accurately.
Conclusion
By following these steps and utilizing the Comp Cams 12-403-8 Solid Lift Cam along with the Edelbrock Performer RPM Intake, you can achieve significant horsepower gains in your Chevy 396. Proper installation and tuning are key to unlocking the full potential of your engine.
