Eagle Pontiac 455 4.500in Crank 6.800in H-Beam -6cc Flat Top 4.155in Pistons Rotating Assembly

Eagle is well-known for building robust rotating assemblies that can handle serious power, and this Pontiac 455 rotating assembly is no exception. If you're building a high-performance Pontiac 455 for racing, especially with nitrous or forced induction, this package is designed to give you a strong foundation. It includes everything you need to get your bottom end built with confidence.

At the heart of this assembly is a 4.500-inch forged 4340 crankshaft, chosen for its strength and durability under high stress. Paired with this are 6.800-inch H-beam connecting rods, which are a popular choice for their solid construction and ability to handle significant loads. These rods come with 7/16-inch ARP 8740 bolts, a name you can trust for reliable clamping force. The pistons are forged 4032 Mahle flat tops with a -6cc dish, designed to work with the 4.155-inch bore size and achieve a specific compression ratio. They also include plasma-moly file-fit rings, which allow for precise gap setting to optimize performance and sealing. To complete the package, King XP rod and main bearings are included, known for their excellent wear resistance and performance in demanding applications.

This rotating assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. It’s a comprehensive kit for anyone looking to build a powerful Pontiac 455 engine that can withstand the rigors of racing.
