BBC H/E Alum. R/A's - 1.7 Ratio 7/16 Stud

The BBC H/E Aluminum Rocker Arms with a 1.7 ratio and 7/16 stud are designed for big-block Chevrolet engine builders who are looking to enhance their engine's performance. These rocker arms are particularly beneficial for applications where stock castings restrict valve lift geometry and duration, making them ideal for both street performance and racing builds.

Constructed from aluminum, these rocker arms provide significant weight savings compared to traditional cast iron options while ensuring the necessary structural integrity for high RPM and demanding valve train conditions. The 1.7 ratio effectively multiplies cam lobe lift, allowing for increased airflow into the cylinders, which is crucial for optimizing engine performance.

These rocker arms are particularly suited for big-block Chevrolet owners utilizing aftermarket or ported cylinder heads with high-lift camshafts. They excel in naturally aspirated performance engines and street/strip builds, where maximizing airflow and efficiency is essential for achieving peak performance.
