Manley Chevrolet Big Block Piston Set - 4.560in Bore 1.520in CH, -3.00 CC

If you're building a high-performance Chevrolet big block engine, these Manley Performance pistons are a solid choice. They're designed for a 4.560-inch bore and feature a 1.520-inch compression height with a -3.00cc dish volume, making them suitable for a wide range of performance applications where precise compression ratios are key.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their exceptional strength and ability to withstand the high stresses of performance engines. The pistons also feature proven cam and barrel skirt profiles. These profiles are carefully machined to reduce friction and wear on the cylinder walls while still generating significant power. The ring lands and grooves are held to very strict tolerances, which is crucial for achieving a good seal with the piston rings, leading to better compression and more power. Manley's unique fixturing process allows them to machine the skirt and ring grooves in the same operation, ensuring the ring grooves are perfectly square to the piston skirt for optimal performance.

This set includes premium chrome moly wrist pins, known for their durability. For those pushing their engines to the absolute limit, Manley offers upgrades to even stronger wrist pin alloys. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are intended for off-road or racing applications where emissions compliance is not a factor.
