Manley Chevrolet Big Block Piston Set - 4.625in Bore 1.270in CH, -3.00 CC

When you're building a serious Chevrolet big block engine, you need pistons that can handle the stress and deliver consistent power. This set from Manley Performance gives you exactly that. You get eight forged pistons, each made from domestic 2618 alloy, which is known for its strength and ability to perform under high loads. They also come standard with chrome moly wrist pins, and Manley's unique fixturing process ensures the ring lands and skirt machining are perfectly square, which is crucial for a good seal and maximum power output.

Manley's signature cam and barrel skirt profiles are designed to generate substantial power while also being gentle on your cylinder walls, reducing wear over time. The ring lands and grooves are machined to exacting standards, which helps ensure a better seal from your piston rings, translating directly into more power and better engine efficiency. These pistons are a popular choice among professional engine builders and tuners who demand reliability and performance from their builds.

This set is designed for a 4.625-inch bore and features a -3.00cc dish volume. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
