Wiseco RED Series Chevy Small Block 350 4.030in Bore 1.250in CH -11.00 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components for performance applications. These RED Series pistons are built for Chevy Small Block 350 engines and are designed to handle the demands of racing and boosted setups. They utilize Race Engineered Design (RED) to give you a competitive edge with precision-machined features.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for performance racing and power adder applications. To ensure optimal lubrication and extend service life, they feature horizontal slot oiling in the pin bores, keeping the wrist pin and small-end well-lubricated. The dedicated forgings allow for an engine-specific strutted design, maximizing strength while keeping weight down. Each set includes premium rings, so you won't need to source those separately, and an accumulator groove helps maintain consistent ring seal and power delivery.

This set is for a 4.030 inch bore with a 1.250 inch compression height and a -11.00cc dish. The pin diameter is 0.927 inches. Please note that these pistons are not CARB approved and cannot be shipped to California. They also carry a Prop 65 warning.
