Manley Chevrolet Small Block Piston Set - 4.035in Bore 1.550in CH, -2.50 CC

If you're rebuilding a Chevrolet small block engine and looking for a solid set of pistons, Manley's Platinum Series pistons are a popular choice among professional builders. This set is designed for a 4.035-inch bore, features a 1.550-inch compression height, and has a -2.50 CC dish, which is important for setting your compression ratio.

These pistons are forged from 2618 alloy, a material known for its strength and ability to handle high performance demands. Manley uses proven cam and barrel skirt profiles, which help the piston move smoothly in the cylinder bore, reducing wear and contributing to power output. The ring lands and grooves are machined to strict standards, ensuring a good seal with your piston rings for optimal combustion efficiency and power. They also come with tool steel wrist pins, and for some applications, upgrades to even stronger alloys are available, adding to their durability.

Manley's manufacturing process includes unique fixturing that allows them to machine the skirt and ring grooves in one operation. This ensures the ring grooves are perfectly square to the piston skirt, which is critical for proper ring seal and engine performance. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine build specifications and manufacturer instructions for proper installation and compatibility.
