What is the purpose of the -31.00 CC dish in these pistons?

The CC (cubic centimeter) rating of a piston dish or dome is crucial for determining your engine's final compression ratio. A negative CC value, like the -31.00 CC dish on these pistons, means the piston top is recessed, which helps lower the compression ratio. This is often used in forced induction (turbo/supercharger) or high-compression naturally aspirated builds to achieve a desired target.

What are the benefits of using forged pistons over cast pistons?

Forged pistons, like these from Manley made with 2618 alloy, are significantly stronger and more durable than cast pistons. They can withstand higher cylinder pressures, temperatures, and stresses, making them essential for high-performance applications such as boosted engines, racing, or engines with aggressive camshafts and high compression ratios.

Are any other wrist pin materials available for these pistons?

While this specific set includes premium chrome moly wrist pins, Manley offers upgrades to 9310 and Turbo Tuff/DLC alloys for select part numbers. These advanced materials provide additional durability for extremely demanding applications.

About this part

Product Details

If you're building a high-performance Chevrolet LS engine, this Manley Piston Set is a solid choice. These pistons are designed for a 4.185-inch bore and feature a -31.00 CC dish, which is important for setting your compression ratio. Manley is a well-known name among professional engine builders, and these pistons are built to handle serious power.

What sets these pistons apart is the material and construction. They're forged from domestic 2618 alloy, which gives them superior strength compared to cast pistons, making them ideal for boosted or high-compression builds. The cam and barrel skirt profiles are carefully designed to help generate power while also being gentler on your cylinder walls, which can extend the life of your engine. Manley also pays close attention to the ring lands and grooves, ensuring a tight seal for better combustion and more power. They even use unique fixturing to machine the skirt and ring grooves in one operation, which helps ensure the ring grooves are perfectly square to the skirt. This level of detail matters for engine longevity and performance.

This set includes premium chrome moly wrist pins, known for their durability. While these are a fantastic option for many LS builds, please note they are not CARB approved and cannot be shipped to California. If you're aiming for serious performance and durability in your LS engine, these Manley pistons are a well-built component to consider.
