Manley Chevrolet Big Block Piston Set - 4.500in Bore 1.270in CH, -20.00 CC

Manley Performance is well-known for making strong engine components, and their Chevrolet Big Block Piston Set is a prime example of that commitment. If you're building a high-performance big block Chevy, these pistons are designed to handle the demands of serious street or track use. They feature a 4.500-inch bore and a -20.00cc dish, making them suitable for specific compression ratio targets in your build.

These pistons are forged from domestic 2618 alloy, a material chosen for its exceptional strength and ability to withstand high cylinder pressures and temperatures. Manley uses proven cam and barrel skirt profiles, which help reduce friction and wear on your cylinder walls while still generating substantial power. The ring lands and grooves are machined to exacting standards, ensuring a tight seal for improved combustion efficiency and more power. They also come standard with chrome moly wrist pins, known for their durability. Manley’s unique fixturing process allows them to machine the skirt and ring grooves in one operation, which guarantees the ring grooves are perfectly square to the skirt for optimal performance.

This set includes pistons designed for an 8-cylinder engine. Please note that these pistons are not CARB approved and cannot be shipped to California. If you're aiming for a robust and powerful Chevrolet Big Block build, these Manley pistons offer a well-built foundation.
