Manley Chevrolet Big Block Piston Set - 4.500in Bore 1.395in CH, 43.00 CC

Manley Performance is well-known for making strong engine components for serious builds. This set of pistons is designed for Chevrolet big block engines and is built using their signature "Platinum Series" construction. They feature 2618 alloy forgings, which are domestic-made and offer superior strength and performance compared to lesser materials. These pistons are a solid choice if you're rebuilding your top end and need parts that can handle the stress of high-performance operation.

You'll find that these pistons have proven cam and barrel skirt profiles, which are shaped to generate substantial power while also being gentle on your cylinder walls. This design helps reduce wear and ensures a smoother operation. Manley also pays close attention to the details, adhering to strict standards for piston ring lands and grooves. This results in an enhanced ring seal, which translates directly to more power. They use unique fixturing that allows for skirt turning and ring groove machining in a single operation, ensuring ultimate ring groove to skirt squareness. Tool steel wrist pins are included, and for select part numbers, upgrades to 9310 and Turbo Tuff/DLC alloys are available for even more durability.

This set is for a 4.500-inch bore with a 1.395-inch compression height and a 43.00 CC combustion chamber volume. Please note that these pistons are not CARB approved and cannot be shipped to California. They also come with a Prop 65 warning.
