Wiseco RED Series Chevy Small Block 400 4.165in Bore 1.000in CH -27.00 CC Piston Set

If you're building a high-performance Chevy Small Block 400, this set of Wiseco RED Series pistons is designed to handle the demands of racing and power adder applications. These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines that see a lot of stress. The RED series stands for Race Engineered Design, meaning Wiseco has put a lot of thought into optimizing these parts for competitive use.

Wiseco machines these pistons in the USA, and they've included several features to ensure durability and performance. You'll find horizontal slot oiling in the pin bores to keep the wrist pins and connecting rod small ends well-lubricated, which is key for long service life. The dedicated forgings allow for an engine-specific strutted design, balancing strength with a manageable weight. Each set comes complete with premium rings, so you won't need to source those separately. An accumulator groove is also included to help maintain consistent ring seal and power output.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're looking for a well-built piston set for a performance build on your Chevy Small Block 400, this Wiseco RED Series set offers a solid foundation.
