Product Details
This is a set of eight CP Pistons BRS forged pistons designed for Small Block Ford engines. These pistons feature a 4.155 inch bore, a 3.400 inch stroke, and are built to work with a 5.400 inch connecting rod. CP Pistons are well-known in the performance engine building world for their robust construction and attention to detail, making them a solid choice when you're aiming for serious power and reliability from your Ford V8.
The BRS series from CP Pistons is engineered for high-performance applications where strength and durability are paramount. These pistons are forged from a strong aluminum alloy, which provides excellent resistance to detonation and fatigue under extreme cylinder pressures. The specific dimensions – a 4.155 inch bore and 3.400 inch stroke – are crucial for achieving a specific displacement and compression ratio when paired with the correct crankshaft and connecting rods. The 5.400 inch rod length is also a key factor in determining piston pin height and overall engine geometry. This set is made to order, meaning it's built specifically for your build, ensuring it meets the exact specifications required for your project. Because they are custom-made, these pistons cannot be canceled once ordered.
When building a high-performance Small Block Ford, choosing the right internal components is critical. These CP Pistons are a significant part of that equation, offering the strength and precision needed for demanding engine builds. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed specifications and installation instructions to ensure proper fitment and performance with your specific engine combination.
