Description

Planning to build your Chevy/Pontiac 5.7L LS motor? These pistons allow of oversized valves and provide maximum airflow around the valve and are designed for higher resistance to detonation and preignition, giving you longer engine life and increase power.

Features

  • Valve Pocket designs that allow maximum flow around valve, also allowing oversized valves and high lift cams to be utilized.
  • Piston Crown shapes designed to promote maximum Intake Charge efficiency through scavenging mixture “Cross Flow” during intake and exhaust valve overlap. More fuel and air equals more horsepower!
  • Piston Domes designed for optimal quench during the compression/ combustion cycle, resulting in resistance to detonation and preignition. The end result is longer engine life and increased horsepower potential.
  • Wiseco’s new ArmorGlide skirt coating is the result of testing, development, and benchmarking through our in-house dyno program. The outcome - minimized friction, maximum horsepower, and improved wear resistance.

Benefits

  • Longer engine life and increased horsepower potential.
  • Maximum ring seal and minimized blow-by and oil consumption.
  • Promote stability in the bore for optimum ring seal.
  • Better ring seal reduces noise from piston rock.
