Upgrading your engine’s camshaft can significantly enhance performance, especially if you’re looking to boost a 350 horsepower engine to over 400 horsepower. With a budget of around $800, you can achieve impressive results that will transform your hot rod. This guide will walk you through the essential elements of selecting and installing a camshaft that meets your performance goals.
Understanding Camshafts
A camshaft is a critical component in your engine that controls the timing and duration of the valve openings. The right camshaft can improve airflow and increase horsepower. When considering a camshaft upgrade, it’s essential to understand the different types available and how they affect engine performance.
Types of Camshafts
- Flat Tappet Camshafts
- Roller Camshafts
- Hydraulic Camshafts
- Solid Camshafts
Each type of camshaft offers different benefits. Flat tappet camshafts are often more affordable and easier to install, while roller camshafts provide better performance and efficiency. Hydraulic camshafts offer a smoother operation, and solid camshafts can provide maximum performance for racing applications.
Choosing the Right Camshaft for Your Engine
When selecting a camshaft, you need to consider several factors that will impact your engine’s performance. These include the engine’s intended use, your horsepower goals, and the characteristics of the camshaft itself.
Key Specifications to Consider
- Lobe Separation Angle (LSA)
- Duration at 0.050” Lift
- Lift
- RPM Range
Understanding these specifications will help you choose a camshaft that matches your engine’s needs. The LSA affects the engine’s idle quality and powerband, while duration and lift influence how much air enters the engine. The RPM range indicates where the camshaft performs best, which is crucial for achieving your horsepower goals.
Recommended Camshafts for 350 HP Engines
Several camshaft options are available that can help you achieve your goal of 400+ horsepower. Here are some popular choices that fit within the $800 budget:
- Comp Cams Xtreme Energy 274H
- Summit Racing SUM-8700
- Edelbrock Performer RPM
- Lunati Voodoo 60103LK
Each of these camshafts is designed to enhance performance and can provide the horsepower increase you’re looking for. Be sure to check compatibility with your engine and other components before making a purchase.
Installation Process
Installing a new camshaft can be a rewarding project, but it requires careful planning and execution. Here’s a basic overview of the installation process:
- Gather Necessary Tools and Parts
- Remove the Old Camshaft
- Prepare the Engine Block
- Install the New Camshaft
- Reassemble the Engine
Make sure to follow the manufacturer’s instructions for specific details related to your camshaft. Proper installation is crucial for achieving optimal performance and avoiding engine damage.
Tuning Your Engine After Installation
After installing a new camshaft, it’s essential to tune your engine to maximize performance. This may involve adjusting the fuel mixture, ignition timing, and other parameters. Consider working with a professional tuner who can help you achieve the best results.
Benefits of Tuning
- Improved horsepower and torque
- Better throttle response
- Increased fuel efficiency
- Enhanced overall performance
Tuning your engine after a camshaft upgrade is vital for ensuring that you get the most out of your investment. A well-tuned engine will perform better and last longer.
Conclusion
Upgrading your camshaft is one of the most effective ways to increase horsepower in your 350 HP engine. With the right camshaft, installation, and tuning, you can easily surpass the 400 HP mark. Remember to choose a camshaft that fits your engine’s needs and your performance goals. Happy hot rodding!
