Manley Chevrolet Big Block Piston Set - 4.500in Bore 1.395in CH, -10.00 CC

When you're building a serious Chevrolet big block engine, you need parts that can handle the stress. This piston set from Manley Performance gives you exactly that. You get eight forged pistons, each designed for a 4.500-inch bore and featuring a -10.00cc dish, which is important for setting your compression ratio. They also come with tool steel wrist pins, which are a solid choice for durability.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to perform under high loads. The skirt profiles are carefully shaped to help generate power while also being considerate of your cylinder walls, reducing wear over time. They also pay close attention to the ring lands and grooves, making sure they're machined to tight tolerances. This is key for getting a good seal from your piston rings, which directly impacts how much power your engine makes and how efficiently it runs.

These pistons are a popular choice among professional engine builders for a reason. The manufacturing process, including how they machine the skirts and grooves in a single operation, ensures that the ring grooves are perfectly square to the piston skirt. This attention to detail means you're getting a well-built component that's ready to go into your performance build. Keep in mind these are not CARB approved and cannot be shipped to California.
