Manley Chevrolet Big Block Piston Set - 4.500in Bore 1.245in CH, 43.00 CC

If you're building a high-performance Chevrolet big block engine, this Manley Performance Piston Set is a solid choice. These pistons are forged from 2618 alloy, a material known for its strength and ability to handle the demands of powerful engines. They feature proven cam and barrel skirt profiles, which help generate power while also being designed to be gentle on your cylinder walls. This means you get performance without unnecessary wear.

Manley puts a lot of attention into the details that matter for engine longevity and power. The ring lands and grooves are machined to exacting standards, which is crucial for a good seal and getting the most power out of your combustion. They use unique fixturing that allows them to machine the skirt and ring grooves in a single operation, ensuring they are perfectly square to each other. This level of precision helps ensure consistent performance and durability over time. The set includes premium chrome moly wrist pins, and depending on the specific SKU, upgrades to even more durable alloys like 9310 and Turbo Tuff/DLC are available for select applications.

This set is designed for a 4.500-inch bore with a 1.245-inch compression height and a 43.00 CC combustion chamber volume. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For serious engine builds, Manley pistons are a popular choice among professional engine builders and tuners who rely on their performance and durability.
