SBC B/I Rocker Arm Kit 1.60 Ratio 7/16 Stud

The SBC B/I Rocker Arm Kit 1.60 Ratio 7/16 Stud from ELGIN is designed specifically for small-block Chevrolet engines, providing reliable valve actuation and precision geometry. This kit is ideal for builders and enthusiasts looking to upgrade their SBC powerplants with higher lift and duration camshafts or replace worn OEM components with quality aftermarket hardware. Whether for street engines, track cars, or restoration projects, this kit meets the durability and performance demands of modern applications.

Featuring a 1.60 rocker arm ratio, this kit amplifies camshaft lift at the valve, extending valve open duration and increasing flow potential compared to stock 1.50 ratios. The 7/16-inch stud mounting pattern is the standard interface for small-block Chevrolet cylinder heads, ensuring compatibility with many aftermarket heads, although specific compatibility should be verified based on head design. ELGIN rockers are machined from high-quality materials with precision valve contact surfaces and hardened pivot points, designed to withstand high RPM cycling without degradation.

Performance builders and mechanics choose this SBC B/I rocker arm kit for restoring or upgrading small-block Chevrolet engines in various applications, including Camaros, Corvettes, and trucks. It is particularly suitable for engines running solid lifter or hydraulic roller camshafts in the 230–280-degree duration range. Proper pushrod length calculation is required for installation to ensure optimal performance.
