Upgrading your B-body vehicle with a performance camshaft can significantly enhance its power and performance. This guide will walk you through the installation process step-by-step, helping you achieve an expected gain of approximately 40 horsepower.
Understanding Camshafts
A camshaft controls the timing and duration of the engine’s intake and exhaust valves. By upgrading to a performance camshaft, you can improve airflow, increase horsepower, and enhance engine responsiveness.
Tools and Materials Needed
- Performance camshaft
- Socket set
- Torque wrench
- Engine oil
- Camshaft installation tool
- Gasket scraper
- New gaskets
- Timing chain or belt (if applicable)
- Shop manual for your B-body
Preparation
Before starting the installation, ensure that your workspace is clean and organized. Gather all necessary tools and materials. It’s also helpful to have your vehicle’s shop manual on hand for reference.
Step-by-Step Installation Process
Step 1: Disconnect the Battery
Safety first! Begin by disconnecting the negative terminal of the battery to prevent any electrical issues during the installation.
Step 2: Remove the Intake Manifold
Carefully remove the intake manifold by unscrewing the bolts and disconnecting any attached components such as vacuum hoses and sensors. Set the manifold aside in a safe location.
Step 3: Access the Camshaft
To access the camshaft, you may need to remove the timing cover. Depending on your engine, this may involve removing the harmonic balancer and other components. Follow your shop manual for specific instructions.
Step 4: Remove the Old Camshaft
Once you have access, unbolt the old camshaft using your socket set. Carefully slide it out of the engine block, ensuring that you do not damage any surrounding components.
Step 5: Prepare the New Camshaft
Before installing the new camshaft, apply a thin layer of engine oil to its bearing surfaces. This will help with lubrication during startup and prevent damage.
Step 6: Install the New Camshaft
Carefully slide the new performance camshaft into the engine block. Make sure it is properly aligned with the camshaft bearings. Secure it in place by tightening the bolts to the manufacturer’s specifications.
Step 7: Reassemble the Engine
Reinstall the timing cover and any components you removed earlier, such as the harmonic balancer. Then, reinstall the intake manifold, ensuring all gaskets are replaced and sealed properly.
Step 8: Reconnect the Battery
Once everything is reassembled, reconnect the negative terminal of the battery. Double-check all connections and ensure nothing is left loose.
Step 9: Start the Engine
Start your engine and allow it to idle for a few minutes. Listen for any unusual noises and check for leaks around the intake manifold and timing cover.
Expected Gains
After installing a performance camshaft, you can expect an increase of approximately 40 horsepower, depending on the specific camshaft and overall engine setup. This upgrade can significantly improve throttle response and acceleration.
Conclusion
Installing a performance camshaft on your B-body is a rewarding project that can lead to substantial performance gains. By following this step-by-step guide, you can successfully enhance your vehicle’s capabilities and enjoy the thrill of driving a more powerful car.
