JE Pistons Chevrolet Big Block 4.310in Bore 1.645in CH -23.00 CC Piston Set

If you're building a Chevrolet Big Block engine for street or strip use and want a solid foundation without breaking the bank, this JE Pistons Sportsman Racing Products piston set is a great place to start. These pistons are designed to give you the strength and performance you need for mild to moderate builds, bridging the gap between basic cast pistons and high-end racing components. They're made to handle the demands of a performance street engine or occasional trips to the drag strip.

Crafted from 4032 aluminum alloy, these pistons offer a good balance of tensile strength and controlled thermal expansion, which helps maintain proper clearances as the engine heats up. This material choice is key for reliability in performance applications. The dedicated forging process optimizes the piston's structure for strength and weight, ensuring they can withstand increased cylinder pressures. You'll also find forced pin oiling, which is a notable feature that improves lubrication to the wrist pin, reducing wear and extending the life of this critical component. All SRP pistons are made 100% in the USA, reflecting a commitment to manufacturing quality.

This set includes eight pistons, each with a 4.310-inch bore and a dome volume of -23.00 CC, designed for an 8-cylinder Chevrolet Big Block engine. Remember that these pistons are not CARB approved and cannot be shipped to California. For a complete engine build, you'll want to ensure you have all the necessary supporting components like rings, connecting rods, and bearings, as these are typically sold separately.
