Preparation

Before starting the installation, ensure that you have a clean workspace and all necessary tools at hand. Read through the instructions provided with the Comp Cams kit carefully to familiarize yourself with the components and steps involved.

Step 1: Remove the Old Camshaft

Begin by disconnecting the battery to prevent any electrical issues. Next, remove the intake manifold and valve covers to access the camshaft. Make sure to label any wires or hoses you disconnect for easier reassembly.

Using a socket set, remove the bolts securing the timing cover and chain. Then, carefully pull out the old camshaft, ensuring that you do not damage the bearings or other components in the process.

Step 2: Prepare the New Camshaft

Before installing the new Comp Cams 454 Roller Cam, apply a liberal amount of engine oil to the camshaft and its bearings. This will help reduce friction during the initial startup and prevent damage.

Step 3: Install the New Camshaft

Carefully insert the new camshaft into the engine block. Use a camshaft installation tool to guide it in place without causing any damage. Make sure the camshaft is aligned correctly with the timing gears.

Step 4: Install the Timing Chain and Gear Set

With the camshaft in place, install the timing chain and gear set according to the manufacturer’s instructions. Ensure that the timing marks are aligned properly for optimal engine performance.

Step 5: Reassemble the Engine

Once the timing chain and gears are secured, reattach the timing cover and valve covers. Replace the intake manifold and reconnect any hoses or wires that were removed. Make sure all bolts are torqued to the manufacturer’s specifications.

Step 6: Final Checks

Before starting the engine, double-check all connections and ensure that everything is properly secured. Check the oil level and add oil if necessary. It’s also a good idea to prime the oil system to ensure that oil reaches the new camshaft before starting the engine.

Step 7: Start the Engine

Reconnect the battery and start the engine. Listen for any unusual noises and watch for leaks. Allow the engine to idle for a few minutes to ensure that everything is functioning correctly.

Step 8: Test Drive

After the engine has warmed up, take the vehicle for a test drive. Pay attention to the performance and responsiveness of the engine. You should notice a significant increase in horsepower and overall performance.

Conclusion

Installing Comp Cams’ 454 Roller Cam can provide impressive horsepower gains and enhance your engine’s performance. By following this step-by-step guide, you can successfully complete the installation and enjoy the benefits of your upgraded camshaft.
