Product Details

The COMP Cams 1266-1 High Energy rocker arm is engineered for 1967-1978 Ford inline-six engines (240 and 300 cubic inch) equipped with 3/8" rocker studs. This precision-manufactured rocker arm features a 1.6:1 ratio, providing increased valve lift compared to stock rockers for improved airflow and performance.

Key Features:

  • 1.6:1 rocker ratio for enhanced valve lift and performance
  • High Energy series construction for durability and reliability
  • Designed specifically for Ford 240-300 inline-six engines (1967-1978)
  • Fits engines with 3/8" rocker arm studs
  • Precision heat-treated steel construction
  • Roller fulcrum design reduces friction and wear

COMP Cams High Energy rocker arms are an excellent upgrade for enthusiasts looking to maximize the performance of their classic Ford inline-six engine. The increased rocker ratio multiplies camshaft lift, allowing for greater valve opening without changing the camshaft itself. These rockers are ideal for street performance applications and work with stock or aftermarket camshafts.
