Wiseco RED Series Chevy Small Block 400 4.165in Bore 1.550in CH -15.00 CC Piston Set

If you're building a high-performance Chevy Small Block 400 for the track, the Wiseco RED Series pistons are a solid choice. These pistons are designed to handle the demands of racing, from drag strips to circle tracks, offering the strength and precision needed to get the most out of your engine. They are forged and machined right here in the USA from 2618 aluminum, a material known for its tensile strength, which is crucial for engines that see a lot of stress and high power output.

Wiseco's Race Engineered Design (RED) process means these pistons aren't just strong; they're also smart. They feature horizontal slot oiling in the pin bores to keep the wrist pins and small-end connecting rods well-lubricated, which is key for long service life under heavy use. The dedicated forgings allow for an engine-specific strutted design, balancing strength with a manageable weight. Plus, the ArmorGlide skirt coating helps cut down on friction and noise, while also reducing wear on the piston skirts and cylinder walls. Each set comes complete with premium rings, so you won't have to hunt for those separately, and an accumulator groove is included to help maintain consistent ring seal and power delivery.

This set is for an 8-cylinder engine with a 4.165-inch bore and a -15.00cc dish, meaning it's designed to work with specific cylinder head volumes to achieve your desired compression ratio. Keep in mind these pistons are not CARB approved and cannot be shipped to California. They are a significant upgrade for any performance engine build where durability and competitive edge are priorities.
