Wiseco Chevy Big Block 4.600in Bore 1.270in CH -19.00 CC Piston Set

Wiseco is well-known for making strong, reliable engine components, especially for high-performance applications. This Professional Series piston set is a prime example, built for serious racers and builders who need top-tier performance and durability in their Chevy Big Block engines. These aren't just any pistons; they're designed from the ground up for heavy to severe duty race builds where every component has to perform under extreme stress.

Forged and machined right here in the USA from 2618 aluminum, these pistons offer improved tensile strength, which is crucial for handling the intense pressures inside a race engine. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, ensuring efficient combustion and preventing detonation. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling further contribute to their ability to withstand demanding performance applications.

This set includes eight pistons, each designed for a 4.600-inch bore with a 1.270-inch compression height and a 0.990-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a race-ready Chevy Big Block, these pistons are a solid option for pushing your engine's limits.
