The Pontiac 400 engine is a classic powerhouse that has been beloved by car enthusiasts for decades. One of the most effective modifications to enhance its performance is the installation of an Edelbrock Performer RPM intake manifold. This article will guide you through the process of installing this intake in approximately three hours, providing you with a step-by-step approach to achieve optimal results.
Tools and Materials Needed
- Edelbrock Performer RPM Intake Manifold
- Intake manifold gasket set
- Torque wrench
- Socket set
- Ratchet
- Flathead screwdriver
- Phillips screwdriver
- Engine cleaner
- Shop towels
- Safety glasses
- Gloves
Preparation Steps
Before diving into the installation process, it’s crucial to prepare your workspace and gather all necessary tools and materials. Follow these steps to ensure a smooth installation:
- Ensure the engine is cool to prevent burns.
- Disconnect the negative battery terminal to avoid electrical issues.
- Remove any components obstructing access to the intake manifold, such as air cleaners and throttle linkages.
- Clean the existing intake manifold with engine cleaner and shop towels to remove any debris or oil.
Removing the Old Intake Manifold
To install the Edelbrock Performer RPM intake, the old intake manifold must first be removed. Follow these steps:
- Use a socket set to remove the bolts securing the old intake manifold.
- Carefully lift the old manifold off the engine, taking care not to damage any surrounding components.
- Inspect the old gaskets and remove any remnants from the engine block.
Installing the Edelbrock Performer RPM Intake
With the old manifold removed, you can now proceed to install the new Edelbrock Performer RPM intake. Follow these steps for a successful installation:
- Place the new intake manifold gasket onto the engine block, ensuring proper alignment with the bolt holes.
- Carefully position the Edelbrock Performer RPM intake manifold onto the gasket.
- Hand-tighten the intake manifold bolts to secure the manifold in place.
- Using a torque wrench, tighten the bolts to the manufacturer’s specifications, typically in a crisscross pattern for even pressure.
Reconnecting Components
After the intake manifold is installed, it’s time to reconnect all components that were removed earlier. Follow these steps:
- Reattach the throttle linkage and any vacuum lines that were disconnected.
- Install the air cleaner back onto the carburetor.
- Reconnect the negative battery terminal.
Final Checks and Testing
Before taking your vehicle for a test drive, it’s essential to perform some final checks:
- Double-check all bolts and connections for tightness.
- Start the engine and let it idle for a few minutes, checking for any leaks or unusual noises.
- Take the vehicle for a short drive to ensure everything is functioning correctly.
Conclusion
Installing an Edelbrock Performer RPM intake manifold on a Pontiac 400 engine is a rewarding modification that can significantly enhance performance. With the right tools, materials, and a clear step-by-step guide, you can complete this installation in approximately three hours. Enjoy the improved power and efficiency of your Pontiac!
