Wiseco RED Series Chevy Small Block 350 4.005in Bore 1.550in CH 3.00 CC Piston Set

This piston set from Wiseco includes eight forged pistons, designed for Chevrolet Small Block 350 engines with a 4.005-inch bore. These are their RED Series pistons, which stand for Race Engineered Design, built to handle the demands of performance racing and power adder applications. They are forged and machined in the USA from 2618 aluminum, a material chosen for its high tensile strength needed in high-performance builds.

Wiseco has incorporated several features to ensure durability and optimal performance. The horizontal slot oiling in the pin bores helps keep the wrist pins and small-end of the connecting rods properly lubricated, which is crucial for a long service life. The pistons themselves use dedicated forgings, allowing for an engine-specific strutted design that maximizes strength while keeping weight down. Additionally, each set comes complete with premium rings, so you won't need to source those separately. The inclusion of an accumulator groove helps maintain consistent ring seal and power output.

These pistons also feature an ArmorGlide skirt coating. This coating is applied to reduce operating friction and noise, while also minimizing wear on both the piston skirt and the cylinder wall. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're building a performance engine for drag racing or circle track, these pistons offer a well-built option with features aimed at giving you a competitive edge.
