The Rocker Arms - SBC 1.6 Ratio 7/16 Stud from Crower are precision-engineered valvetrain components designed specifically for small-block Chevy (SBC) engines. They provide reliable valve actuation for builders and mechanics focused on dependable performance without the added complexity or cost of roller conversions. This makes them an excellent choice for budget-conscious restorations and stock rebuilds.
These stamped steel rockers feature a 1.6 mechanical advantage ratio, which increases valve lift and duration compared to stock 1.5 ratio arms, enhancing cylinder head breathing and engine responsiveness. The durable construction ensures hassle-free installation on existing cylinder heads with a 7/16-inch stud mounting interface, adhering to industry standards. This design minimizes deflection under valve spring pressure, reducing wear on pushrods and valve stems.
Ideal for SBC engine builders working with 283, 302, 327, 350, or 400 displacement variants, these rocker arms are compatible with stock or performance camshafts up to moderate lift specifications. Installation is straightforward and requires only basic hand tools, making them accessible for both novice and experienced mechanics.
