CP Piston BRS Small Block Ford 4.045 Bore 3.500 Stroke 6.200 Set Of 8 (MTO Non-Cancel)

If you're building a high-performance Small Block Ford engine, getting the right pistons is crucial for reliability and power. This set from CP Pistons is designed for serious builds where strength and precision are paramount. These are forged pistons, meaning they start as a solid block of aluminum that's heated and hammered into shape under immense pressure. This process creates a much stronger and more durable piston than cast aluminum, making them ideal for engines that will see high RPMs, boost, or nitrous.

This specific set features a 4.045-inch bore and a 3.500-inch stroke, with a 6.200-inch compression height. The compression height is the distance from the center of the wrist pin bore to the top of the piston, and it's critical for achieving the correct compression ratio with your cylinder heads and crankshaft. CP Pistons are well-known for their tight tolerances and consistent manufacturing, which helps ensure each piston in the set is virtually identical. This uniformity is key for balanced engine operation and predictable performance. Because these are made-to-order, you can be confident they are built to the exact specifications required for your custom engine build.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are also a made-to-order item and cannot be canceled once the order is placed. Ensure you have the correct supporting components, such as matching connecting rods and cylinder heads, to achieve your desired engine displacement and compression ratio.
