What is the compression ratio impact of the -20.00cc dish?

The -20.00cc dish is a significant factor in determining your engine's final compression ratio. The exact impact will depend on your cylinder head volume, head gasket thickness, and deck height. This dish volume is designed to lower compression, making it suitable for forced induction applications or specific naturally aspirated builds.

What is included with this piston set?

This set includes the pistons, tool steel wrist pins, and skirt coatings where applicable. You will need to source piston rings separately, as they are not included with this kit.

Are these pistons suitable for a turbo or supercharged engine?

Yes, the 2618 alloy forgings and robust construction make these pistons well-suited for high-performance applications, including those with turbochargers or superchargers. The -20.00cc dish is often used to achieve a lower compression ratio, which is beneficial for boosted engines.

About this part

Product Details

If you're building a high-performance Chevrolet LS engine, this Manley Performance piston set is a solid choice. These pistons are designed for a 4.165-inch bore and feature a -20.00cc dish, which is crucial for setting your compression ratio. Manley is a well-known name among professional engine builders, and these pistons are part of their signature "Platinum Series," meaning they're built to handle serious power and last.

What sets these pistons apart starts with the material: they're forged from domestic 2618 alloy. Forging makes them much stronger and more durable than cast pistons, essential when you're pushing an engine hard. They also feature proven cam and barrel skirt profiles, which help them run smoothly and quietly while still making good power. Manley pays close attention to the details, like the ring lands and grooves, ensuring a tight seal for better combustion efficiency. The included wrist pins are made from tool steel for added strength, and Manley's unique manufacturing process ensures the ring grooves are perfectly square to the piston skirt for optimal performance.

This set includes pistons, tool steel wrist pins, and skirt coatings on select parts, ready for your build. Remember that these pistons are not CARB approved and cannot be shipped to California. If you're aiming for serious power and reliability in your LS engine, these Manley pistons are a well-built foundation.
