Manley Chevrolet Big Block Piston Set - 4.500in Bore 1.645in CH, -10.00 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 designed with a 4.500-inch bore and a -10.00cc dish volume, which is crucial for setting your compression ratio. They also feature a 1.645-inch compression height, meaning the distance from the wrist pin center to the piston crown is precisely controlled for proper valve clearance and deck height.

Manley uses their signature 2618 alloy forgings for these pistons, a material known for its exceptional strength and ability to withstand high temperatures and pressures. This makes them a solid choice for performance builds where durability is just as important as power. The pistons come with tool steel wrist pins, and the skirt profiles are carefully shaped to reduce friction and wear on your cylinder walls while still generating substantial power. Manley also pays close attention to the ring lands and grooves, ensuring a tight seal for improved combustion efficiency and more horsepower.

This set includes eight pistons, eight tool steel wrist pins, and the necessary ring sets to complete the installation. Manley's unique manufacturing process ensures the ring grooves are perfectly square to the piston skirt, which is vital for optimal ring seal. These pistons are not CARB approved and cannot be shipped to California. They are designed for serious engine builders looking for reliable performance and longevity in their Chevrolet big block builds.
