B-body Mopar Performance Camshaft Swap: Step-by-step Installation and Power Gains

The B-body Mopar performance camshaft swap is a popular modification among enthusiasts looking to enhance the performance of their vehicles. This guide will take you through the step-by-step process of installing a new camshaft and the potential power gains you can expect.

Understanding Camshafts

A camshaft is a crucial component in an engine that controls the timing and duration of valve openings and closings. Upgrading to a performance camshaft can significantly improve engine efficiency, horsepower, and torque.

Benefits of a Camshaft Swap

  • Increased Horsepower: A performance camshaft can provide a noticeable boost in horsepower.
  • Improved Torque: Enhanced torque can lead to better acceleration and overall performance.
  • Better Engine Sound: A performance camshaft can give your engine a more aggressive sound.
  • Enhanced Throttle Response: A new camshaft can improve throttle response, making your vehicle feel more responsive.

Preparing for the Swap

Before starting the camshaft swap, ensure you have the necessary tools and parts. Here’s a list of what you’ll need:

  • New performance camshaft
  • Timing chain or belt (if applicable)
  • Gaskets and seals
  • Engine oil
  • Basic hand tools (sockets, wrenches, screwdrivers)
  • Torque wrench
  • Engine assembly lubricant

Step-by-Step Installation Process

Step 1: Preparation

Begin by disconnecting the battery and draining the engine oil. This will help prevent any electrical shorts and ensure a clean workspace.

Step 2: Remove the Old Camshaft

To access the camshaft, you will need to remove the intake manifold, valve covers, and timing chain or belt. Take care to label and organize all components for reassembly.

Step 3: Install the New Camshaft

Carefully lubricate the new camshaft with engine assembly lubricant. Align it with the timing marks and install it into the engine, ensuring it is seated correctly.

Step 4: Reassemble the Engine

Reinstall the timing chain or belt, valve covers, and intake manifold. Make sure to use new gaskets and seals to prevent leaks.

Step 5: Add Engine Oil and Reconnect the Battery

Fill the engine with fresh oil and reconnect the battery. This step is crucial for ensuring proper lubrication during the initial startup.

Step 6: Start the Engine

Start the engine and let it idle for a few minutes. Listen for any unusual noises and check for leaks. It’s essential to monitor the engine closely during this initial period.

Expected Power Gains

After completing the camshaft swap, you can expect significant power gains. Depending on the camshaft specifications and supporting modifications, horsepower increases of 20 to 50 horsepower are common.

Conclusion

The B-body Mopar performance camshaft swap is a rewarding project that can yield impressive results. By following this step-by-step guide, you can enhance your vehicle’s performance and enjoy the benefits of a more powerful engine.
