CP Piston BRS Chevy 359Ci 23 4.040 Bore 1.250 Ch -4.9CC Flat Top - Set Of 8 (MTO Non-Cancel)

These CP Pistons are forged from high-strength aluminum, a material chosen for its excellent strength-to-weight ratio, which is critical for high-performance engine builds. The 4.040-inch bore size is a common upgrade for many Chevy V8 applications, and these pistons are specifically designed for 359 cubic inch displacements, featuring a flat-top design with a -4.9cc dish. This configuration is often selected to achieve a desired compression ratio when paired with specific cylinder heads and head gasket thicknesses.

The 1.250-inch compression height is another key measurement, determining the piston's position in the cylinder bore relative to the crankshaft centerline at Top Dead Center. This precise measurement ensures proper valve clearance and piston-to-head clearance, which are vital for engine longevity and performance. CP Pistons are known for their tight tolerances and consistent manufacturing, meaning you get a well-built set that fits right and performs reliably. This set includes eight pistons, enough for a complete V8 engine rebuild.

Because these pistons are made-to-order, they are non-cancelable once production begins. Please verify your engine's specific requirements and intended build before ordering. Note that these pistons are not CARB approved and cannot be shipped to California.
