The Chevy 350 engine is a popular choice among car enthusiasts and builders due to its versatility and performance potential. One of the modifications that can significantly enhance its performance is the installation of a Crane Cams hydraulic roller camshaft. This article explores how much horsepower a Crane Cams hydraulic roller can add to your Chevy 350, along with the benefits and considerations of this upgrade.
Understanding the Chevy 350 Engine
The Chevy 350 is a small-block V8 engine that has been in production since the mid-1960s. Known for its robust design and reliability, the 350 engine has become a staple in many classic cars and trucks. Its ability to produce substantial horsepower and torque makes it a favorite for performance enthusiasts.
What is a Hydraulic Roller Camshaft?
A hydraulic roller camshaft uses roller lifters, which reduce friction and allow for more precise valve timing. This design offers several advantages over traditional flat-tappet camshafts, including:
- Increased horsepower and torque
- Improved fuel efficiency
- Longer lifespan due to reduced wear
- Better throttle response
How Much Horsepower Can You Expect?
The horsepower gain from installing a Crane Cams hydraulic roller camshaft on a Chevy 350 can vary based on several factors, including the specific cam profile, supporting modifications, and tuning. However, on average, you can expect a horsepower increase in the range of:
- 25 to 50 horsepower with a mild cam profile
- 50 to 75 horsepower with a more aggressive cam profile
Factors Influencing Horsepower Gains
Several factors can influence the actual horsepower gains you experience after installing a hydraulic roller camshaft:
- Cam Profile: The lift and duration of the camshaft play a critical role in determining horsepower gains.
- Supporting Modifications: Upgrades such as headers, intake manifolds, and carburetors can enhance performance.
- Tuning: Proper tuning of the engine management system is essential to maximize horsepower gains.
- Engine Condition: The overall health of the engine can affect performance outcomes.
Benefits of Upgrading to a Hydraulic Roller Camshaft
Upgrading to a Crane Cams hydraulic roller camshaft offers several benefits beyond just horsepower gains:
- Better Performance: Hydraulic roller camshafts provide improved performance across the RPM range.
- Enhanced Reliability: Reduced wear on engine components leads to a longer lifespan.
- Improved Fuel Economy: More efficient combustion can result in better fuel economy.
- Smoother Idle: Many hydraulic roller camshafts provide a smoother idle compared to flat-tappet designs.
Installation Considerations
When considering the installation of a hydraulic roller camshaft, keep the following points in mind:
- Compatibility: Ensure that the camshaft is compatible with your specific Chevy 350 engine setup.
- Professional Installation: If you are not experienced, consider hiring a professional for installation to avoid potential issues.
- Break-In Procedure: Follow the manufacturer’s break-in procedure to ensure proper camshaft performance.
- Supporting Parts: You may need to upgrade other components such as lifters, pushrods, and springs to accommodate the new camshaft.
Conclusion
Installing a Crane Cams hydraulic roller camshaft can significantly enhance the performance of your Chevy 350 engine. With potential horsepower gains ranging from 25 to 75 horsepower, along with improved reliability and efficiency, this upgrade is an excellent choice for enthusiasts looking to boost their engine’s performance. By considering the factors influencing horsepower gains and ensuring proper installation, you can enjoy the full benefits of this performance enhancement.
