CP Piston BRS BBC 13.0CC Dome 4.600 Bore 4.250 Stroke 6.385 Rod Set Of 8 (MTO Non-Cancel)

CP Pistons is well-known for making high-performance internal engine components, and this set of forged pistons for Big Block Chevy engines is a prime example of their work. If you're building a serious performance engine, these pistons are designed to handle the demands of high horsepower and torque applications. They feature a 13.0cc dome volume, which is crucial for achieving specific compression ratios when paired with the right cylinder heads and gasket thickness. The bore size is 4.600 inches, the stroke is 4.250 inches, and they are designed to work with a 6.385-inch connecting rod, making them a key component for a custom engine build.

These pistons are forged from high-strength aluminum alloy, a common practice for performance pistons because it offers a better strength-to-weight ratio compared to cast aluminum. This means they can withstand the extreme pressures and temperatures found in a high-performance engine without deforming or failing. The BRS designation indicates a specific design series from CP Pistons, often focusing on durability and performance for racing or extreme street use. Because these are made-to-order (MTO), they are built to your specifications and cannot be canceled once production begins, ensuring you get exactly what you need for your build.

This set includes eight pistons, as required for a V8 engine. When planning your build, remember to consider the necessary supporting components such as piston rings, wrist pins, and connecting rods, which are typically sold separately. Proper balancing of the rotating assembly is also critical for engine longevity and smooth operation at high RPMs. Due to their specialized nature and MTO status, these pistons are not CARB approved and cannot be shipped to California.
