The BBF Rocker Arms - 1.73 Ratio 7/16 Stud are designed for builders and enthusiasts focused on enhancing valve train performance in big-block Ford engines. These rocker arms are essential for any cam swap or cylinder head upgrade, as they directly influence the relationship between camshaft lift and valve opening geometry.
With a 1.73 rocker arm ratio, these components multiply camshaft lift, providing a significant mechanical advantage that enhances valve velocity and dwell time. The 7/16 stud design ensures compatibility with modern aftermarket cylinder heads, while the construction is tailored to withstand high-RPM operation and aggressive valve spring pressures.
Ideal for Big Block Ford applications, including 385-series engines like the 460 and 429, these rocker arms allow for improved performance over stock 1.6 ratio arms. Installers should verify compatibility with their specific engine setup to maximize performance potential.
