  • Small Block Chevy W/AFR 227 Cylinder Heads
  • 1.5 Ratio
  • .050 in. Offset
  • 7/16 in. Stud

    The pushrod cups have been moved .050 to the left & right, on the intake rockers, so special guide plates will be needed.

arland Sharp developed and manufactured the first aluminum needle bearing Roller Tip Rocker Arms in 1960. Since then, thousands of racing enthusiasts have experienced the quality and precision of every Harland Sharp rocker arm. Features include full needle bearing roller fulcrum, roller tip, and consistent ratios to reduce friction, wear, and to stabilize valve timing. The unique Friction-Free design offers average gains of 15-40 HP. Head-specific rockers are designed for a perfect fit, thus eliminating valve guide wear and friction for maximum horsepower.

  • Offset roller & offset pushrod cups allow for perfect alignment & geometry for custom cylinder heads
  • Eliminate valve guide wear and friction due to misalignment
