Product Details

The Lunati 85027 is a stamped steel replacement rocker arm designed for big block Chevrolet V8 engines including 396, 427, and 454 cubic inch applications. Engineered for reliable performance in stock rebuilds and mild performance builds, this rocker arm delivers proven durability at an economical price point.

Key Features:

  • Stamped steel construction with heat treatment to prevent flexing and distortion
  • 1.7:1 rocker ratio for stock replacement applications
  • 0.560-inch maximum valve lift capacity
  • 7/16-inch stud mounting design
  • Long slot design accommodates higher-than-stock valve lift
  • Sold individually for precise replacement needs

Manufactured from quality steel alloy, this rocker arm is heat treated to maintain rigidity under demanding valve train loads. The extended slot design provides additional clearance for performance camshafts with increased lift specifications. Popular in oval track racing where rules mandate stock-appearing rocker arms, the Lunati 85027 offers dependable performance for street engines and entry-level competition applications.
