Wiseco Chevy 305 3.796in Bore 1.250in CH -3.00 CC Piston Set

If you're rebuilding the engine in your Chevrolet 305 for serious racing or heavy-duty performance, a strong set of pistons is crucial. This Wiseco Professional Series piston set is built to handle the demands of severe duty applications. Each piston is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high stress.

These pistons feature precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is critical for consistent power and engine health under extreme conditions. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and contributes to quieter operation, all important factors when you're pushing an engine hard. The fully machined crown ensures accuracy and proper combustion chamber volume, and forced pin oiling helps keep the wrist pins lubricated.

This set includes eight pistons, each with a 3.796-inch bore, 1.250-inch compression height, and a -3.00cc dish volume. Remember that these pistons are not CARB approved and cannot be shipped to California. For a robust engine build designed for performance, this Wiseco set is a solid option.
