Manley Chevrolet Big Block Piston Set - 4.500in Bore 1.520in CH, 43.00 CC

If you're building a high-performance Chevrolet big block engine, this Manley Performance piston set is a solid choice. These pistons are designed for a 4.500-inch bore and feature a 1.520-inch compression height with a 43.00 CC combustion chamber volume. Manley is a well-known name among professional engine builders for a reason – their parts are built to handle serious power and deliver consistent performance.

What sets these pistons apart is the material they're made from: domestic 2618 alloy forgings. This alloy is chosen for its strength and ability to withstand the high pressures and temperatures found in performance engines. They also feature proven cam and barrel skirt profiles, which help reduce friction and wear on your cylinder walls while still making good power. The ring lands and grooves are machined to very tight tolerances, which is crucial for getting a good seal from your piston rings, leading to more efficient combustion and better power output. You'll also find that Manley's manufacturing process ensures the ring grooves are perfectly square to the piston skirt, which is another detail that contributes to a long-lasting, high-performing engine.

This set includes tool steel wrist pins, and depending on the specific part number, some may come with upgraded wrist pin alloys for even more durability. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For serious engine builds, Manley pistons are a popular option that many rely on for their performance and durability.
