What is the compression dish volume and why does it matter?

This piston set has a -2.50 CC dish volume. This volume is subtracted from the combustion chamber volume (cylinder head, head gasket, and deck clearance) to determine the final compression ratio of your engine. A larger dish generally lowers compression, while a smaller dish or dome raises it.

What material are the pistons made from and what are the benefits?

These pistons are forged from domestic 2618 alloy. This material is known for its superior strength and durability, making it well-suited for high-performance applications where pistons are subjected to significant stress and heat.

Are these pistons compatible with all piston rings?

The ring lands and grooves are machined to exacting standards to ensure enhanced ring seal. While they are designed for optimal performance with quality piston rings, it's always best to confirm ring compatibility based on your specific engine build and desired ring gap.

About this part

Product Details

Manley Performance is well-known for building serious engine components, and their Platinum Series pistons are a prime example of that commitment. If you're building a Chevrolet Small Block engine and need pistons that can handle the demands of performance, this set is designed to meet those needs. They feature a 4.035-inch bore and a -2.50 CC dish, which is a specific volume that affects your compression ratio when paired with your cylinder heads and head gasket.

These pistons are forged from domestic 2618 alloy, a material chosen for its exceptional strength and ability to perform under high stress. Manley also uses proven cam and barrel skirt profiles, which are shaped to help generate power efficiently while also being designed to minimize wear on your cylinder walls. The ring lands and grooves are machined to very precise standards, which is crucial for achieving a good seal with your piston rings, ultimately leading to more power and better engine efficiency. They also come with premium Chrome Moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the piston skirts, a detail that contributes to overall engine health and performance.

When you're putting together a high-performance engine, the details matter. These pistons are a solid choice for builders looking for durability and performance from a trusted name in the industry. Keep in mind that these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
