The Chevy Small Block 350 is one of the most popular engines in automotive history, known for its versatility and performance potential. For enthusiasts looking to unlock an additional 75-100 horsepower, selecting the right camshaft and lifter combination is crucial. In this article, we will explore some of the best camshaft and lifter combos that can help you achieve significant power gains.
Understanding Camshaft Basics
A camshaft controls the timing and duration of the engine’s intake and exhaust valves. The right camshaft can enhance engine performance by improving airflow and optimizing combustion. Key factors to consider include:
- Lift: The distance the valve is opened, affecting airflow.
- Duration: The time the valve stays open, influencing engine RPM range.
- Overlap: The period when both intake and exhaust valves are open, impacting engine efficiency.
Choosing the Right Lifters
Lifters play a critical role in the camshaft’s performance. They transfer the camshaft’s motion to the valves. There are two main types of lifters:
- Hydraulic Lifters: Self-adjusting and provide a quieter operation.
- Solid Lifters: Offer better performance at high RPMs but require more maintenance.
