Wiseco Chevy Big Block 4.350in Bore 1.270in CH 45.00 CC Piston Set

When you're building a serious performance engine for your Chevrolet Big Block, you need components that can handle the stress. This piston set from Wiseco gives you eight forged pistons, ready to be installed in your 4.350-inch bore engine. These aren't just any pistons; they're part of Wiseco's Professional Series, meaning they're built with no compromises for demanding race applications.

Each piston is forged and machined right here in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high loads. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal and keep combustion contained. Wiseco also applies an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. The fully machined crown and forced pin oiling further demonstrate the attention to detail in these pistons, ensuring they can withstand the rigors of heavy to severe duty performance builds.

This set includes everything needed to outfit an 8-cylinder engine. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
