About this part

Product Details

If you're building a serious performance Chevrolet Big Block engine, especially for racing or heavy-duty applications, these Wiseco pistons are a solid choice. They're designed to handle the extreme demands of severe duty builds, offering improved strength and durability where it counts. This set is for a 4.560-inch bore with a 1.065-inch compression height, fitting a wide range of Chevrolet vehicles from the early 70s like the Impala and Chevelle, through later models like the C1500 and Express 3500 vans.

Wiseco forges these pistons in the USA from 2618 aluminum, a material known for its high tensile strength, which is crucial for withstanding the intense pressures and heat generated in a high-performance engine. They feature precision-machined ring grooves, anti-detonation grooves, and other features to improve ring seal and prevent detonation. The crown of each piston is fully machined, and they come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and operate more quietly, all while the forced pin oiling system ensures the wrist pins stay well-lubricated under load.

This set includes eight pistons, ready to be installed in your Big Block Chevy. Remember to consult the manufacturer's installation instructions for proper fitment and assembly procedures, as these are critical for achieving the intended performance and longevity in a race-oriented build.
