What materials are these pistons made from?

These Manley pistons are forged from a domestic 2618 alloy, which is known for its superior strength and performance characteristics. They also include premium chrome moly wrist pins.

What is the significance of the cam and barrel skirt profiles?

The cam and barrel skirt profiles are designed to help the piston generate substantial power while also minimizing wear on the cylinder walls. This contributes to a longer engine life and consistent performance.

Are these pistons compatible with all Chevrolet Big Block engines?

This specific set is designed for a 4.600 inch bore size. While it's intended for Chevrolet Big Block engines, you must confirm that your engine's bore diameter and other specifications, like compression height, match these pistons for proper fitment.

About this part

Product Details

When you're building a serious Chevrolet big block engine, you need components that can handle the stress and deliver consistent power. This set of Manley Performance pistons, part number 697980-8, is designed for builders who demand reliability and performance. You get four pistons, each measuring 4.600 inches in bore diameter, with a 1.120-inch compression height and a 43.00 cubic centimeter volume in the combustion chamber. These are forged from a domestic 2618 alloy, a material known for its exceptional strength, making them well-suited for high-performance applications where durability is key.

Manley has incorporated proven cam and barrel skirt profiles into these pistons. This design helps them generate substantial power while also being gentle on your cylinder walls, reducing wear over time. The ring lands and grooves are machined to exacting standards, which is crucial for achieving a better ring seal. A good ring seal means more efficient combustion and, ultimately, more power from your engine. Each set also includes premium chrome moly wrist pins, adding to the overall durability and reliability of the assembly. Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single operation, ensuring perfect squareness between the ring grooves and the piston skirt.

This piston set is a solid option for anyone rebuilding or upgrading their Chevrolet big block engine. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have the correct rings and connecting rods that match the piston specifications, including the 1.120-inch compression height and the 4.600-inch bore size.
