This high-performance valvetrain system utilizes a robust belt-driven design manufactured by Jesel for Big Block Ford (BBF) engines. It replaces the traditional chain or gear-driven camshaft actuation with a toothed belt, offering advantages in terms of reduced friction, improved timing accuracy, and increased horsepower potential. This system is typically found in high-performance or racing applications where these benefits are crucial for maximizing engine output and reliability.
Reduced harmonic vibrations, a common issue with chain systems, contribute to more stable valve timing at higher RPM. This stability allows for more aggressive camshaft profiles and higher engine speeds, translating to increased power and a broader power band. Furthermore, the lower frictional losses compared to traditional methods free up horsepower that would otherwise be consumed driving the valvetrain. This technology represents a significant advancement in valvetrain design for BBF engines, contributing to increased performance capabilities in demanding motorsport environments.
