CP Piston BRS Chevy 357Ci 23 4.030 Bore 1.250 Ch -4.9CC Flat Top - Set Of 8 (MTO Non-Cancel)

If you're building a high-performance Chevy engine, especially one aiming for around 357 cubic inches with a 4.030-inch bore, this set of CP Pistons is a solid choice. These are forged pistons, which means they start as a solid block of aluminum that's heated and hammered into shape under immense pressure. This process creates a much stronger and more durable piston than cast aluminum, making them ideal for engines that will see hard use or higher compression ratios. The flat-top design with a -4.9cc dish is a common configuration that works well with many different cylinder head combinations, allowing for precise tuning of your compression ratio. This set includes eight pistons, enough for a full V8 engine.

CP Pistons is known for making well-built components for racing and performance applications. These pistons feature a 1.250-inch compression height, which is the distance from the wrist pin center to the top of the piston. This measurement is critical for ensuring proper piston-to-valve clearance and deck height in your engine build. Because these pistons are made to order, they offer a unique opportunity to get exactly what you need for your specific build, but it also means they are non-cancelable once ordered. This ensures you're getting a fresh, custom-made part for your project.

When planning your engine build, remember that these pistons are sold as a set of eight. You'll also want to ensure you have the correct wrist pins, locks, and rings to match the piston specifications, as these are typically sold separately. Always refer to the manufacturer's detailed specifications and installation guide to confirm compatibility with your specific crankshaft, connecting rods, and cylinder heads to achieve the desired compression ratio and performance.
