What material are these pistons made from?

These Manley "Platinum Series" pistons are forged from domestic 2618 alloy. This material is chosen for its superior strength and performance characteristics, making it well-suited for demanding engine applications.

What is the purpose of the -4cc dish?

The -4cc dish is a feature that helps control the engine's compression ratio. By creating a slight volume in the piston crown, it can be used to lower the overall compression when paired with specific cylinder heads and head gaskets.

Are rings and bearings included with this piston set?

This set includes the pistons and tool steel wrist pins. Rings and bearings are typically sold separately and should be chosen based on your specific engine build requirements and clearances.

About this part

Product Details

If you're building a Small Block Chevy engine and need a solid set of pistons, these Manley Performance "Platinum Series" units are a strong contender. They're designed for a 4-inch bore and feature a -4cc dish, making them suitable for a variety of performance builds where you need to control compression ratio. Manley has been a go-to for serious engine builders for a long time, and these pistons reflect that experience.

What sets these apart is the material and the machining. They're forged from domestic 2618 alloy, which is known for its strength and ability to handle the stresses of a performance engine. You also get tool steel wrist pins included, which are robust enough for most applications. Manley also pays close attention to the details, like the ring lands and grooves, ensuring a good seal for better power. Plus, their unique machining process means the ring grooves are perfectly square to the piston skirt, which helps with both sealing and reducing wear on the cylinder walls.

These pistons are a great starting point for a performance Small Block Chevy build. They're well-made and designed to perform. Just remember that they are not CARB approved, so they can't be shipped to California. You'll also want to check the manufacturer's instructions for the correct installation procedures and any other components you might need, like rings and bearings, which are typically sold separately.
