Manley Chevrolet Big Block Piston Set - 4.560in Bore 1.120in CH, 43.00 CC

If you're building a high-performance Chevrolet big block engine, Manley's 697960-8 piston set is a solid choice. These pistons are forged from 2618 alloy, a material known for its strength and ability to handle the stresses of powerful engines. They're designed with proven cam and barrel skirt profiles, which help generate power while also being considerate of your cylinder walls during operation. This attention to detail means you're getting a well-built component that's ready for serious work.

Manley takes precision seriously with these pistons. They adhere to strict standards for the ring lands and grooves, which is crucial for achieving a good seal and maximizing the power your engine can produce. The unique fixturing Manley uses allows them to machine the skirt and ring grooves in one operation, ensuring they are perfectly square to each other. This level of accuracy contributes to better performance and longevity. Each set includes tool steel wrist pins, and depending on the specific SKU, upgrades to even more durable alloys like 9310 or Turbo Tuff/DLC are available, offering additional peace of mind for demanding builds.

This piston set is intended for engine builders and tuners who rely on robust components for their projects. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
