CP Piston BRS Chevy 434Ci All 23 4.155 Bore 1.000 Ch -20.6CC - Set Of 8 (MTO Non-Cancel)

If you're building a high-performance Chevy engine, especially one aiming for around 434 cubic inches with a 4.155-inch bore, a solid set of pistons is crucial. These CP Pistons BRS series pistons are designed for those demanding builds where strength and reliability under extreme conditions are paramount. They are made from well-built forged aluminum, which is significantly stronger and more durable than cast aluminum, allowing them to withstand the higher pressures and temperatures found in performance applications.

This set includes eight pistons, each featuring a 4.155-inch bore and a 1.000-inch compression height. The pistons have a -20.6cc dish volume, which is important for calculating your final compression ratio when paired with your specific cylinder heads and crankshaft. The BRS series is known for its robust construction, making them a popular choice for engine builders who need parts that can handle serious power. Remember, these are a made-to-order item and cannot be canceled once ordered, so ensure they are the correct specification for your build.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always consult with your engine builder or refer to manufacturer specifications to confirm compatibility with your specific engine components and to determine the correct compression ratio for your intended use.
