Manley Chevrolet Big Block Piston Set - 4.500in Bore 1.520in CH, -20.00 CC

When you're building a serious Chevrolet big block engine, you need components that can handle the stress and deliver reliable power. This piston set from Manley Performance is designed for just that. You get a complete set of four pistons, each forged from 2618 alloy, which is known for its strength and ability to withstand high performance demands. They also include tool steel wrist pins and a moly skirt coating to help with durability and reduce friction.

Manley uses domestic 2618 alloy forgings for these pistons, giving you a solid foundation for your engine build. The pistons feature proven cam and barrel skirt profiles, which are shaped to help generate power while also being kind to your cylinder walls. This attention to detail extends to the ring lands and grooves, which are machined to exacting standards to ensure a better seal for your piston rings, ultimately leading to more power. Manley's unique machining process allows them to turn the skirts and machine the ring grooves in one operation, ensuring the ring grooves are perfectly square to the skirt for optimal performance.

This set is intended for a 4.500-inch bore with a -20.00cc dish, a common configuration for many high-performance big block builds. If you're looking to rebuild your top end with components trusted by professional engine builders and tuners, this Manley piston set is a well-built option.
