Manley Chevrolet Big Block Piston Set - 4.560in Bore 1.270in CH, 43.00 CC

If you're rebuilding the heart of your Chevrolet Big Block engine and aiming for serious performance, a solid set of forged pistons is where you start. This Manley Performance Piston Set is built for those who demand strength and reliability under high stress, whether you're building a race motor or a potent street machine.

Manley uses domestic 2618 alloy forgings, which are known for their exceptional strength and ability to handle the heat and pressure of a performance engine. These pistons feature proven cam and barrel skirt profiles designed to generate power efficiently while also being gentle on your cylinder walls, which helps with longevity. The ring lands and grooves are machined to exacting standards, ensuring a tight seal for maximum power output. For added durability, they come standard with chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, contributing to overall engine health and performance.

This set is designed for a 4.560-inch bore and has a 1.270-inch compression height with a 43.00 CC combustion chamber volume. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have the correct rings and bearings to match, as well as follow the manufacturer's installation guidelines carefully.
