If you're building a high-performance Chevy 454 for serious racing, this Eagle competition rotating assembly is a solid foundation. It's designed to handle the stresses of racing, including nitrous and forced induction applications, giving you the confidence to push your engine hard.

This assembly starts with a 4.000-inch forged 4340 crankshaft, known for its strength and durability under extreme loads. Paired with it are 6.135-inch H-beam connecting rods, which are a popular choice for their robust design. These rods are secured with 7/16-inch ARP 8740 bolts, a name trusted for reliable fastener performance in high-stress environments. The pistons are forged 2618 ICON units, featuring a 27cc closed chamber dome design and a 4.250-inch bore size, tailored for specific compression ratios. You also get plasma-moly file-fit piston rings, allowing for precise gap setting to match your engine's bore and intended use, along with King XP rod and main bearings to ensure smooth rotation and proper oil clearance.

This is a comprehensive package designed for builders who demand reliable performance from their engines. Remember that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
