The JE Pistons 329507S are SRP Professional series forged pistons designed for Small Block Chevrolet 350/400 engines. These pistons are made from high-silicon 4032 aluminum alloy, offering superior strength and up to 20% lighter weight compared to traditional equivalent pistons. They feature accumulator grooves for improved ring seal and are suitable for normally aspirated or moderate forced induction nitrous engine applications. The pistons come with a high-performance skirt coating and a low drag performance metric ring package (1.2mm Carbon Steel top ring, 1.5mm Napier 2nd ring, 3.0mm standard tension oil ring) for improved oil control. They require minimal filing and include high-quality 2.250" wrist pins and carbon steel wire locks. These pistons are designed to work with Chevy 23-degree cylinder heads with 20/30 valve spacing.
