BBC Rocker Arms - 1.7 Ratio 7/16 Stud

The BBC Rocker Arms - 1.7 Ratio 7/16 Stud are designed for serious big-block Chevy builders who demand precise valve control and durability. Ideal for high-performance street and competition engines, these rocker arms are engineered to handle increased valve lift and aggressive cam profiles.

The 1.7:1 ratio enhances camshaft lift at the valve, maximizing flow through larger ports and improving breathing capacity without excessive camshaft lift. The 7/16-inch stud design provides a secure mounting interface that resists deflection under valve spring pressure, maintaining valve timing accuracy across various engine loads.

These rocker arms are perfect for big-block Chevy engines ranging from 396 to 502 cubic inches and are compatible with modern hydraulic roller camshafts, mechanical roller setups, and traditional flat-tappet profiles. They offer the mechanical advantage and consistency required for reliable performance in both street and competition applications.
