CP Piston BRS Big Block 4.610 Bore 4.250 Stroke 6.385 Rod 1.275 Set Of 8 (MTO Non-Cancel)

This is a set of CP Pistons BRS Big Block pistons, designed for high-performance engine builds. These pistons are specifically made for a 4.610 inch bore with a 4.250 inch stroke, and they utilize a 6.385 inch rod length. Each piston in this set of 8 features a 1.275 inch compression height, which is crucial for achieving the correct deck height and compression ratio in your engine build. CP Pistons are well-known in racing circles for their robust construction and precision manufacturing, making them a popular choice for serious engine builders.

These pistons are forged from high-strength aluminum alloy, a common practice for performance pistons because it offers a strong yet lightweight component. This strength is essential for handling the extreme pressures and temperatures found in high-performance big block engines. The BRS series from CP Pistons is engineered to offer improved durability and performance over stock cast pistons. They are designed to work with specific rod lengths and crankshaft strokes to achieve optimal engine geometry and performance characteristics. The 1.275 inch compression height is a key measurement that dictates how the piston crown sits relative to the cylinder block deck at Top Dead Center, directly impacting your engine's compression ratio and valve-to-piston clearance.

This set is made to order (MTO) and is non-cancelable once production begins, so please confirm all specifications before ordering. They are not CARB approved and cannot be shipped to California. If you're building a powerful big block engine where reliability and performance are paramount, these CP Pistons offer a solid foundation.
