Wiseco Chevy Big Block 4.530in Bore 1.270in CH -19.00 CC Piston Set

If you're rebuilding the heart of a Chevy Big Block for serious racing or heavy-duty performance, a strong set of pistons is where you start. This Wiseco Professional Series piston set is built from the ground up for demanding applications. They're forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength over standard aluminum alloys, making them well-suited for the stresses of high-performance engines.

Wiseco has packed these pistons with features to handle severe duty. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. The fully machined crown ensures accuracy, and they come with forced pin oiling to keep things well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and resist seizure, contributing to quieter operation and better durability under load.

This set is designed for an 8-cylinder engine with a 4.530-inch bore and a -19.00cc dish, giving you a specific compression ratio target. Remember, these are intended for racing and heavy-duty builds, so they're not CARB approved and cannot be shipped to California. For a robust foundation in your next performance engine build, this Wiseco set is a solid option.
