About this part

Product Details

If you're building a high-performance Chevy 454 engine for serious racing, a strong rotating assembly is the heart of the operation. This Eagle Competition Rotating Assembly is designed to handle the demands of competition, whether you're running naturally aspirated, nitrous, or forced induction setups. It's a well-built foundation that lets you push your engine's limits.

This assembly starts with a forged 4340 steel crankshaft featuring a 4.250-inch stroke, providing the displacement needed for big power. Connecting the crank to the pistons are 6.385-inch H-beam connecting rods, known for their strength and reliability under stress. These rods are secured with 7/16-inch ARP 8740 bolts, a popular choice for their durability and consistent clamping force. The pistons are forged 4032 aluminum from ICON, featuring a 23cc dome shape and a 4.310-inch bore size, designed to work with the crank and rods for optimal compression and performance. They come complete with plasma-moly file-fit rings, allowing for precise gap setting to match your engine's specific needs and boost levels. To ensure smooth operation and proper lubrication, the assembly includes King XP rod and main bearings, which offer robust performance for demanding applications.

This rotating assembly is a comprehensive package for anyone serious about building a powerful and reliable engine. It's important to note that this part is not CARB approved and cannot be shipped to California due to emissions regulations.
