The Comp Cams 427 Hydraulic Roller Camshaft upgrade is a popular choice among car enthusiasts looking to enhance their vehicle’s performance. This article provides a comprehensive guide on the installation steps and the performance boosts you can expect from this upgrade.
What is a Hydraulic Roller Camshaft?
A hydraulic roller camshaft is a type of camshaft that uses hydraulic lifters to maintain contact with the cam lobes. This design reduces friction and allows for greater RPM capabilities compared to traditional flat-tappet camshafts. The Comp Cams 427 Hydraulic Roller Camshaft is specifically designed for high-performance engines, providing improved throttle response and power output.
Benefits of Upgrading to a Hydraulic Roller Camshaft
- Increased Power: The hydraulic roller camshaft offers better airflow and more aggressive lift profiles, resulting in increased horsepower and torque.
- Better Efficiency: The design reduces friction, leading to improved fuel efficiency and engine longevity.
- Improved Throttle Response: Enhanced cam timing results in quicker engine response, making the vehicle more enjoyable to drive.
- Lower Maintenance: Hydraulic lifters require less adjustment compared to solid lifters, making maintenance easier.
Installation Steps for the Comp Cams 427 Hydraulic Roller Camshaft
Tools and Materials Needed
- Socket set
- Torque wrench
- Camshaft installation tool
- Engine oil
- New camshaft bearings
- New lifters
- Timing chain or belt
- Gasket set
Step 1: Preparation
Before starting the installation, ensure that the engine is cool and disconnected from the battery. Remove any accessories that may obstruct access to the camshaft.
Step 2: Remove the Old Camshaft
Drain the engine oil and remove the oil pan if necessary. Take off the timing cover and remove the timing chain or belt. Unbolt the old camshaft and carefully lift it out of the engine block.
Step 3: Install New Camshaft Bearings
Using a camshaft bearing installer, press the new camshaft bearings into the engine block. Ensure they are properly aligned and seated.
