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

This piston set features a -10.00cc dish volume. The dish volume, along with the cylinder head's combustion chamber volume and the head gasket thickness, determines the engine's final compression ratio. A dish volume typically lowers the compression ratio, which can be useful for forced induction applications or when using heads with very large combustion chambers.

What type of wrist pins are included with this piston set?

This specific set comes standard with premium chrome moly wrist pins. These are strong and durable, suitable for many performance applications. Manley also offers upgraded wrist pin options like 9310 and Turbo Tuff/DLC alloys on select part numbers for even greater durability.

Are these pistons coated?

The manufacturer description mentions that select Manley 'Platinum Series' pistons feature moly skirt coatings. While this specific set is part of the 'Platinum Series,' the input data does not explicitly state if this particular SKU (696560-8) includes the moly skirt coating. It's best to confirm with Manley Performance directly if this feature is critical for your build.

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 is designed for just that. You get eight pistons, each forged from domestic 2618 alloy, known for its exceptional strength and ability to perform under high loads. They feature a 4.560-inch bore size and a -10.00cc dish volume, which is a common configuration for many performance builds, especially those looking to achieve a specific compression ratio with a particular head chamber volume.

Manley has put a lot of thought into the design of these pistons. They use proven cam and barrel skirt profiles, which help the piston move smoothly in the cylinder while minimizing wear on the cylinder walls. This design also contributes to generating more power. The ring lands and grooves are machined to very strict standards, which is crucial for getting a good seal from your piston rings, leading to better compression and more power. Each set also includes tool steel wrist pins, a strong component for connecting the piston to the connecting rod, ensuring durability in high-RPM applications.

For those looking to push their engine even further, Manley offers upgrades for the wrist pins on some of their piston lines, though this specific set comes standard with chrome moly wrist pins. The manufacturing process itself is notable; Manley uses unique fixturing that allows them to machine the skirt and the ring grooves in one operation. This ensures the ring grooves are perfectly square to the piston skirt, which is essential for optimal ring seal and overall engine performance. These pistons are a solid choice for anyone serious about building a reliable and powerful Chevrolet big block.
