When it comes to enhancing the performance of your Chevy Nova, selecting the right aftermarket camshaft is crucial. Two popular options among enthusiasts are the Crane 274H and the Comp Cams Xtreme 4×4. Both camshafts offer unique benefits and can significantly impact your vehicle’s power output. In this article, we will compare these two camshafts to help you make an informed decision.
Overview of Aftermarket Camshafts
Aftermarket camshafts are designed to improve engine performance by altering the timing and duration of the engine’s valve openings. This can lead to increased horsepower and torque, better throttle response, and enhanced overall driving experience. Choosing the right camshaft depends on various factors, including your engine setup, intended use, and personal preferences.
Crane 274H Camshaft
The Crane 274H camshaft is a popular choice for those looking to boost the performance of their Chevy Nova. It is designed for street and strip applications, providing a balance between power and drivability.

The specifications of the Comp Cams Xtreme 4×4 indicate a camshaft that is more aggressive, designed to maximize power in specific applications, especially for those who prioritize off-road performance.
Power and Performance Comparison
When comparing the Crane 274H and the Comp Cams Xtreme 4×4 camshafts, several factors come into play regarding power and performance.
Horsepower and Torque
The Crane 274H camshaft generally provides a higher peak horsepower in the mid to upper RPM range, making it an excellent choice for those who enjoy spirited driving and track days. In contrast, the Comp Cams Xtreme 4×4 camshaft excels in delivering torque at lower RPMs, making it ideal for off-road scenarios and heavy loads.
Throttle Response
Throttle response is another critical factor in performance. The Crane 274H offers a more linear throttle response, which is beneficial for street driving.

The Crane 274H is relatively straightforward to install, making it a good choice for enthusiasts who want to upgrade without extensive modifications.
Comp Cams Xtreme 4×4 Installation Requirements
- Requires upgraded valve springs for optimal performance
- Best suited for modified engines
- May require custom tuning for best results
Installation of the Comp Cams Xtreme 4×4 can be more complex, requiring additional upgrades and tuning to fully realize its potential.
Cost Considerations
Cost is always a consideration when upgrading your vehicle. Both camshafts vary in price based on the supplier and any additional components you may need for installation.
