CP Piston BRS BBC 24.9CC Dome 4.530 Bore 4.500 Stroke 6.700 Rod Set Of 8 (MTO Non-Cancel)

If you're building a high-performance Big Block Chevrolet engine, getting the right pistons is crucial for reliability and power. This set from CP Pistons is designed for serious builds, featuring a 24.9cc dome that helps achieve a specific compression ratio when paired with the correct cylinder heads and gasket thickness. The 4.530-inch bore size is common for many stroker combinations, and these pistons are intended to work with a 4.500-inch stroke crankshaft and a 6.700-inch connecting rod, making them a key component for a custom engine assembly.

These pistons are forged from a strong aluminum alloy, which is a standard practice for high-stress performance applications because it offers a better strength-to-weight ratio than cast pistons. This means they can withstand the intense pressures and heat generated in a powerful engine. The dome shape is carefully calculated to work with specific combustion chamber volumes, influencing how the fuel and air mixture burns. Because these are made to order, they are built to precise specifications, ensuring they fit right and perform as intended in your custom engine build. Remember, these are non-cancelable once ordered, so double-check your measurements and build plan before purchasing.

This set includes eight pistons, enough for a complete V8 engine. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or a trusted professional to ensure these pistons are the correct choice for your specific engine combination and performance goals.
