If you're building a high-performance naturally aspirated 454 big-block Chevy for racing, a solid rotating assembly is the heart of your engine. This Pro Street rotating assembly from Eagle is designed to handle the demands of serious competition, providing a strong foundation for your build.

This assembly starts with a 4.000-inch stroke forged 4340 steel crankshaft, known for its strength and durability under high stress. Paired with it are 6.135-inch 4340 steel I-beam connecting rods, which are a popular choice for their balance of strength and weight. These rods come equipped with 7/16-inch ARP 8740 bolts, a well-respected name in high-strength fasteners, ensuring a secure connection. The pistons are forged 4032 aluminum from ICON, featuring a 4.310-inch bore and a closed chamber dome design with an 18.3cc volume, which is crucial for achieving the desired compression ratio with specific cylinder heads. The assembly also includes plasma-moly file-fit piston rings, allowing for precise gap setting to match your engine's bore and intended use, and King XP series rod and main bearings, offering robust performance for demanding applications.
