When it comes to enhancing the performance of your Firebird, upgrading the camshaft is one of the most impactful modifications you can make. Among the various options available, Crane Cams has established a reputation for quality performance camshafts. This article will delve into the performance improvements you can expect when upgrading to a Crane Cam, focusing on power gains, torque increases, and overall engine efficiency.
Understanding Camshaft Functionality
The camshaft plays a crucial role in the engine’s performance by controlling the timing and duration of the valve openings. This, in turn, affects the air-fuel mixture entering the combustion chamber. An upgraded camshaft can significantly enhance engine performance by allowing more air and fuel to enter, resulting in increased horsepower and torque.
