CP Piston BRS SBC 417Ci Ascs 4.140 Bore 1.062 Ch 13.8:1 Cr - Set Of 8 (MTO Non-Cancel)

This order gets you a complete set of eight CP Pistons Billet Series pistons, specifically designed for a 417 cubic inch Small Block Chevy (SBC) engine build. These aren't just any pistons; they're forged from high-strength aluminum to handle the demands of a high-compression, performance-oriented engine. With a 4.140-inch bore and a 1.062-inch pin diameter, they are built for precision fitment within your engine block and connecting rods.

The Billet Series designation means these pistons are machined from a solid block of aluminum, offering exceptional strength and durability compared to cast or hypereutectic pistons. This robust construction is crucial for achieving and maintaining a 13.8:1 compression ratio, which is ideal for maximizing power output in naturally aspirated or forced induction applications where premium fuel is used. The specific dish volume and crown design are engineered to work with specific cylinder head chamber volumes to achieve this target compression. Each piston features a specific skirt design and coating (if applicable, though not specified here) to reduce friction and wear, contributing to overall engine longevity and performance.

It's important to note that these pistons are made-to-order and are non-cancelable once the order is placed, so double-check your specifications before confirming. Also, these pistons are not CARB approved and cannot be shipped to California due to emissions regulations. For a build targeting significant power and requiring a high-compression setup, this set of CP Pistons offers a well-built foundation.
