Manley Chevrolet Big Block Piston Set - 4.530in Bore 1.520in CH, 43.00 CC

Manley Performance is well-known for building strong, reliable engine components for serious racers and builders. This set of Chevrolet Big Block pistons, part number 697730-8, is a prime example of their commitment to performance. These aren't just any pistons; they're forged from 2618 alloy, a material chosen for its exceptional strength and ability to handle the high stresses found in performance big block engines. If you're rebuilding a Chevrolet big block and demand robust internals, these pistons are designed to meet that need.

What sets these pistons apart is the attention to detail in their design and manufacturing. They feature proven cam and barrel skirt profiles, which help them run smoothly and quietly while minimizing wear on your cylinder walls. The ring lands and grooves are machined to exacting standards, which is crucial for achieving a tight seal with your piston rings. This improved ring seal means more consistent compression and ultimately, more power. Manley's unique fixturing process allows them to machine the skirt and ring grooves in one go, ensuring they are perfectly square to each other for optimal performance.

Included with these pistons are premium chrome moly wrist pins, known for their durability. For those pushing the limits, Manley offers upgrades to even stronger wrist pin alloys. This piston set is a solid foundation for a high-performance big block build, offering the strength and precision that professional engine builders rely on. Please note that these pistons are not CARB approved and cannot be shipped to California.
