Manley Chevrolet Big Block Piston Set - 4.530in Bore 1.645in CH, -10.00 CC

Built with domestic 2618 alloy forgings, these Manley pistons are crafted for serious Chevrolet Big Block builds. The 4.530-inch bore size and -10.00cc dish volume are key specifications for achieving a specific compression ratio in your engine, and the 1.645-inch compression height is crucial for proper valve-to-piston clearance and deck height.

Manley's signature cam and barrel skirt profiles are designed to reduce friction and wear on your cylinder walls while still generating substantial power. They've also paid close attention to the ring lands and grooves, holding them to strict standards to ensure an enhanced ring seal, which directly translates to more power output. The included chrome moly wrist pins are well-built for durability, and for those looking for even more resilience, Manley offers upgrades to 9310 and Turbo Tuff/DLC alloys on select part numbers.

The unique fixturing Manley uses allows them to machine the skirt and cut the ring grooves in a single operation. This ensures the ring grooves are perfectly square to the piston skirt, which is vital for optimal ring seal and engine performance. These pistons are a popular choice among professional engine builders and tuners who demand reliability and power from their builds.
