Manley Chevrolet Big Block Piston Set - 4.560in Bore 1.645in CH, -3.00 CC

This set includes eight forged pistons from Manley Performance, designed for Chevrolet big block engines. Each piston has a 4.560-inch bore diameter, a 1.645-inch compression height, and a -3.00cc dish volume. These pistons are built using Manley's signature Platinum Series construction, featuring domestic 2618 alloy forgings known for their exceptional strength and performance under demanding conditions. They also come standard with premium chrome moly wrist pins, which offer solid durability for most builds. If you're looking for pistons that professional engine builders trust for serious performance and longevity, these are a well-built option.

Manley pays close attention to the details that make a difference in engine power and reliability. The ring lands and grooves are machined to strict standards, which helps ensure a better seal for the piston rings, leading to more efficient combustion and increased power output. The pistons feature proven cam and barrel skirt profiles, designed to generate substantial power while also being gentle on your cylinder walls, reducing wear over time. This careful profiling, combined with Manley's unique fixturing process that allows skirt turning and ring groove machining in a single operation, ensures ultimate squareness between the ring grooves and the piston skirt. This precision contributes to a more consistent and powerful engine build.

When building a high-performance engine, the pistons are a critical component. These Manley pistons are a solid choice for those seeking robust performance and durability. Please note that these pistons are not CARB approved and cannot be shipped to California. It's always recommended to consult your engine builder or refer to Manley's installation guidelines for specific details regarding assembly and break-in procedures.
