CP Piston BRS Big Block Pontiac 4.155 Bore 4.250 Stroke 6.800 Rod Set Of 8 (MTO Non-Cancel)

This is a set of eight forged pistons from CP Pistons, specifically made for Big Block Pontiac engines. These pistons are designed for a 4.155 inch bore and feature a 4.250 inch stroke with a 6.800 inch rod length. Because these are made to order, they offer a unique opportunity to get precisely what your high-performance engine build needs. CP Pistons is well-known in racing circles for their commitment to precision and durability, and this set is no exception. They are built from strong aluminum alloys that can handle the extreme pressures and temperatures found in powerful V8 engines.

The BRS series pistons are engineered for serious performance applications. The forged construction means they are significantly stronger and more resistant to detonation than cast pistons, which is crucial when you're pushing the limits of a big block engine. The specific dimensions – 4.155" bore, 4.250" stroke, and 6.800" rod length – are critical for achieving the correct compression ratio and displacement for your specific Pontiac build. It's important to note that these pistons are made to order and cannot be canceled once production begins, so double-check your measurements before ordering. Also, be aware that these are not CARB approved and cannot be shipped to California.

When building a high-performance engine, the pistons are one of the most critical components. Choosing a well-built set like these from CP Pistons ensures that your engine can reliably produce power. Make sure you have all the necessary supporting components for your build, as these pistons are just one part of a complex system. Always refer to your engine builder's specifications and the manufacturer's installation guidelines for proper fitment and assembly.
