What is the compression ratio impact of the -31.00 CC dish volume?

The -31.00 CC dish volume on these pistons is designed to lower the compression ratio. The exact impact on your engine's compression ratio will depend on the combustion chamber volume of your cylinder heads and the thickness of your head gasket.

What type of piston rings are recommended for this set?

Manley Performance pistons are designed for optimal ring seal with high-quality piston rings. It is recommended to use a ring set specifically designed for a 4.080 inch bore and the corresponding ring land dimensions specified by Manley for this piston model.

Are these pistons suitable for a daily driver or a dedicated race engine?

These pistons are built with 2618 alloy forgings and features like moly skirt coatings, making them well-suited for high-performance and racing applications where durability under extreme stress is critical. While they can be used in a street-driven vehicle, they are engineered for demanding use.

About this part

Product Details

If you're rebuilding the heart of your Chevrolet LS engine for serious performance, a strong set of pistons is where you start. This Manley Performance piston set is built using domestic 2618 alloy forgings, a material known for its exceptional strength and ability to handle the demands of high-output engines. The 4.080-inch bore size and -31.00 CC dish volume are specific to certain LS engine builds, often used to achieve a desired compression ratio when paired with specific cylinder heads.

Manley's attention to detail is evident in the cam and barrel skirt profiles, which are designed to reduce friction and wear on your cylinder walls while still generating significant power. They also hold exacting standards for the ring lands and grooves, which is crucial for achieving a tight seal with your piston rings. This precise machining helps ensure you get every bit of power out of your engine and keeps blow-by to a minimum. The included tool steel wrist pins are well-built for durability, and the moly skirt coatings on select part numbers further enhance longevity and reduce friction.

This set is a popular choice among professional engine builders and tuners who rely on Manley for consistent performance and durability. It's important to note 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, especially when determining the correct ring set and bearing clearances for your specific build.
