Wiseco 4.630 Big Block Chevy Quick 16 +45cc Dome 1.270CH Piston Set

If you're building a serious performance Big Block Chevy engine, Wiseco's Professional Series forged pistons are a solid option. This set is designed for a 4.630 inch bore and features a +45cc dome, intended for high-compression racing applications. They're made from 2618 aluminum, which is well-known for its improved tensile strength, making these pistons tough enough for heavy to severe duty race builds.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features that improve ring seal. They also come with an ArmorGlide skirt coating. This coating helps reduce friction and resist seizure, while also contributing to quieter operation. The fully machined crown and forced pin oiling are further touches that show these are built for demanding performance.

This is a set of 8 pistons. Keep in mind that these are not CARB approved and cannot be shipped to California. For serious engine builds, these pistons offer a well-built foundation.
