CP Piston BRS SBC 416Ci Ascs 4.135 Bore 1.062 Ch 13.8:1 Cr - Set Of 8 (MTO Non-Cancel)

This is a set of eight CP Pistons Billet Racing Series (BRS) pistons, specifically designed for a 416 cubic inch Small Block Chevrolet (SBC) engine build. These pistons are crafted to achieve a 13.8:1 compression ratio with a 4.135-inch bore and a 1.062-inch compression height. CP Pistons is a well-known name in high-performance engine components, and this set represents their commitment to building robust parts for demanding applications.

These pistons are forged from high-strength aluminum, a common practice for racing pistons because it offers a good balance of durability and weight. The Billet Racing Series designation suggests these are made from a solid billet block of aluminum, which is then machined to shape. This process results in a very strong and consistent piston structure, capable of withstanding the extreme pressures and temperatures found in a high-performance engine. The 4.135-inch bore size is specific to certain engine configurations, and the 13.8:1 compression ratio indicates these are intended for naturally aspirated or forced induction applications where maximum power output is the goal. The 1.062-inch compression height is also a critical dimension that determines the piston's position in the cylinder relative to the crankshaft, affecting valve timing and piston-to-head clearance.

It's important to note that these pistons are made to order and are non-cancelable once the order is placed. This means you should be certain of your engine specifications before purchasing. Also, these pistons are not CARB approved and cannot be shipped to California. If you are building a high-performance SBC engine and need a strong, reliable piston set that is precisely manufactured, this CP Pistons set is a solid option.
