About this part

Product Details

This is a set of eight CP Pistons Bullet Race Series pistons, designed for Small Block Ford engines. You get the pistons themselves, ready to be installed in your performance build. These pistons feature a 4.125 inch bore, a 4.000 inch stroke, and are designed to work with a 6.200 inch connecting rod. They are a standard size, meaning they are meant for a fresh bore or a block that has already been machined to this specific size.

CP Pistons is known for making well-built internal engine components, and this Bullet Race Series set is no exception. They are forged from high-strength aluminum, which gives them the durability needed to handle the stresses of a high-performance engine. The forged construction means they are less prone to cracking or deforming under extreme cylinder pressures and temperatures compared to cast pistons. This makes them a solid choice for builders looking to push the limits of their Small Block Ford, whether for drag racing, road racing, or serious street performance.

When building a performance engine, the pistons are a critical component. These CP Pistons are designed to be a direct fit for the specified bore size and rod length, simplifying the assembly process for experienced engine builders. 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 machinist to ensure these pistons meet the specific requirements of your project and that all necessary clearances and tolerances are met during assembly.
