Product Details

The COMP Cams High Energy Aluminum Roller Rocker Arms deliver enhanced performance and durability for Big Block Chevy 396-454 engines. Featuring a precision 1.7:1 ratio, these rocker arms increase valve lift to optimize airflow and boost horsepower output compared to stock 1.5 ratio rockers.

Key Features:

  • CNC-machined aluminum body for lightweight strength and heat dissipation
  • Needle bearing fulcrum design reduces friction and wear
  • Roller tip minimizes valve stem side loading and improves valve guide life
  • 1.7:1 rocker ratio increases valve lift by approximately 13% over stock
  • Designed for 7/16" rocker studs (standard BBC configuration)
  • Compatible with Big Block Chevy 396, 402, 427, and 454 cubic inch engines
  • Self-aligning design compensates for minor valvetrain geometry variations

These High Energy rocker arms are an excellent upgrade for street performance and mild racing applications. The aluminum construction reduces valvetrain weight while the roller tip and needle bearings ensure smooth, reliable operation at elevated RPM. Sold individually - order 16 pieces for a complete V8 engine set.
