Installing a COMP Cams Xtreme Energy Cam on a 427 engine can significantly enhance performance and power output. This guide provides a detailed step-by-step process along with power test results to help you achieve optimal results.
Tools and Materials Needed
- COMP Cams Xtreme Energy Cam kit
- Socket set
- Torque wrench
- Timing light
- Engine oil
- Gasket set
- Ratcheting wrenches
- Camshaft installation tool
Preparation Steps
Before starting the installation, ensure that your engine is cool and that you have a clean workspace. Gather all the tools and materials listed above.
Removing the Old Camshaft
1. Disconnect the battery to avoid any electrical issues during the installation.
2. Remove the intake manifold and valve covers to access the camshaft.
3. Unbolt the timing chain cover and remove the timing chain.
4. Carefully remove the old camshaft, taking note of the position of the timing marks.
Installing the COMP Cams Xtreme Energy Cam
1. Apply assembly lube to the new camshaft and its bearings.
2. Using the camshaft installation tool, carefully insert the new camshaft into the engine block.
3. Align the timing marks on the camshaft and crankshaft.
4. Reinstall the timing chain and cover, ensuring proper tension.
Reassembly of Engine Components
With the new camshaft installed, it’s time to reassemble the engine.
Reinstalling the Valve Covers and Intake Manifold
1. Place a new gasket on the valve covers and securely bolt them back into place.
2. Install the intake manifold, ensuring that all bolts are torqued to the manufacturer’s specifications.
Final Checks and Adjustments
1. Reconnect the battery and check all electrical connections.
2. Set the timing with a timing light according to the camshaft specifications.
3. Check for any leaks around the valve covers and intake manifold.
Power Test Results
After the installation, it’s essential to test the power output of the engine to evaluate performance improvements.
Testing Procedure
1. Use a dynamometer to measure the engine’s horsepower and torque before and after the camshaft installation.
2. Record the RPM at which peak power occurs.
Results Overview
Before the installation, the engine produced 400 horsepower at 5500 RPM and 450 lb-ft of torque. After installing the COMP Cams Xtreme Energy Cam, the results showed:
- Peak horsepower: 450 at 6000 RPM
- Peak torque: 480 lb-ft at 4800 RPM
This resulted in a significant improvement in both horsepower and torque, showcasing the effectiveness of the COMP Cams Xtreme Energy Cam.
Conclusion
Installing a COMP Cams Xtreme Energy Cam on a 427 engine can dramatically enhance performance. Following the step-by-step guide ensures a successful installation, leading to impressive power test results.
