The Plymouth Barracuda, a classic American muscle car, has captured the hearts of automotive enthusiasts since its inception. One of the most effective ways to enhance its performance is through camshaft upgrades. This article explores the journey from stock camshafts to high-performance options that can yield over 25 horsepower increases.
Understanding Camshafts
Camshafts play a crucial role in the engine’s performance by controlling the timing and duration of the valve openings. This directly affects the engine’s ability to breathe, thus influencing horsepower and torque. Upgrading the camshaft can significantly improve engine efficiency and power output.
Stock Camshaft Specifications
The stock camshaft in a Plymouth Barracuda is designed for balanced performance and fuel efficiency. However, it often limits the engine’s full potential. Understanding the specifications of the stock camshaft is essential for evaluating upgrade options.
- Lift: Typically around 0.410 inches
- Duration: Approximately 260 degrees
- Overlap: Minimal, around 50 degrees
Benefits of Camshaft Upgrades
Upgrading the camshaft can lead to several benefits, including:
- Increased horsepower and torque
- Improved throttle response
- Enhanced engine sound
- Better overall performance
Choosing the Right Camshaft
When selecting a camshaft for your Barracuda, consider the following factors:
- Engine type and size
- Intended use (street, track, or racing)
- Compatibility with other engine components
- Desired power band and performance characteristics
Popular Camshaft Upgrades for Plymouth Barracuda
Several aftermarket camshafts are popular among Barracuda enthusiasts. Here are a few options that can provide significant horsepower gains:
- Comp Cams Xtreme Energy: Known for its aggressive lift and duration, this camshaft can increase horsepower by 25+.
- Summit Racing Camshaft: A budget-friendly option that offers a noticeable performance boost.
