Step-by-Step Installation Process
Preparation
Before beginning the installation, ensure your engine is cool. Disconnect the battery to prevent any electrical issues. Gather all your tools and materials for a smooth installation process.
Removing the Old Intake Manifold
Start by removing any components that obstruct access to the intake manifold, such as the air cleaner, carburetor, and any vacuum lines. Next, unbolt the existing intake manifold using a socket set. Carefully lift it off, making sure not to drop any debris into the engine.
Preparing the New Intake Manifold
Before installing the Holley Street Dominator, clean the engine’s surface where the manifold will sit. Apply a thin layer of engine oil to the new gaskets to ensure a proper seal. Position the gaskets onto the engine, aligning them with the bolt holes.
Installing the Holley Street Dominator Intake
Carefully place the Holley intake manifold onto the gaskets. Ensure it is aligned correctly with the bolt holes. Hand-tighten the bolts initially, then use a torque wrench to tighten them to the manufacturer’s specifications, usually in a crisscross pattern for even pressure.
Reconnecting Components
Reattach the carburetor, air cleaner, and any vacuum lines you removed earlier. Make sure everything is secure and properly connected. Double-check your work to ensure no tools or parts are left in the engine bay.
Final Checks
Reconnect the battery and start the engine. Listen for any unusual sounds and check for leaks around the intake manifold. Allow the engine to reach operating temperature and ensure it runs smoothly.
Conclusion
Upgrading to a Holley Street Dominator intake manifold can significantly improve the performance of your Chevy 350. With increased horsepower, better torque, and enhanced throttle response, this modification is a worthwhile investment for any enthusiast. Follow the installation steps carefully, and enjoy the benefits of your upgraded engine.
