Product Details
If you're building a high-performance Chevy engine for racing or serious street use, you're probably looking at forged pistons to handle the extra stress. These CP Pistons BRS series pistons are designed for just that. They're built for 420 cubic inch (420Ci) Chevy applications, with a 4.165-inch bore and a substantial 14.6:1 compression ratio. This setup is ideal for naturally aspirated engines looking to maximize power output.
CP Pistons is known for making well-built components for demanding builds. These particular pistons feature a BRS design, which is a specific forging that CP uses for strength and weight optimization. The 1.062-inch compression height means they're designed to work with specific crankshaft stroke and connecting rod lengths to achieve that 14.6:1 compression ratio. Remember, these are made to order and cannot be canceled once placed, so double-check your engine specs before ordering.
This set includes eight pistons, enough for a full V8 engine. Because these are custom-made, they are not CARB approved and cannot be shipped to California. Be sure to confirm all your engine dimensions, including stroke and rod length, to ensure these pistons will achieve your desired compression ratio and piston-to-valve clearance.
