What is the purpose of the -10.00cc dish in these pistons?

The dish in the piston crown is used to control the engine's compression ratio. A negative dish (a dish) reduces the volume in the combustion chamber, lowering the compression ratio. This is essential when matching pistons to specific cylinder heads and head gaskets for your desired performance level.

What are the benefits of using 2618 alloy forgings?

2618 alloy is a popular choice for high-performance pistons because it offers excellent strength and ductility. This means it can withstand high temperatures and pressures without fracturing, making it ideal for demanding engine builds.

Are the wrist pins included with this piston set?

Yes, this Manley piston set includes tool steel wrist pins, which are known for their durability and ability to handle high loads within the engine.

About this part

Product Details

If you're rebuilding or upgrading your Chevrolet LT1 engine for serious performance, a strong set of pistons is where it all starts. This Manley Piston Set is built to handle the demands of a high-output engine, whether you're building a track car or a powerful street machine. These pistons are designed to work with a 4.080-inch bore and feature a -10.00cc dish, which is crucial for setting your compression ratio correctly with your chosen cylinder heads and gasket combination.

Manley uses domestic 2618 alloy forgings for these pistons, a material known for its exceptional strength and ability to withstand high temperatures and pressures. They also feature proven cam and barrel skirt profiles, which help reduce friction and wear on your cylinder walls while still allowing the piston to generate substantial power. The ring lands and grooves are machined to very strict standards, which is key for getting a good seal from your piston rings, ultimately leading to more power and better efficiency. For added durability, these pistons come with tool steel wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the piston skirt, which is vital for consistent ring seal under load.

This set includes eight pistons, each ready to be installed in your LT1 engine. Remember 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 details, especially regarding ring gap, piston-to-wall clearance, and wrist pin installation.
