Eagle Pontiac 400 4.500in Crank 6.800in H-Beam -24cc 4.160in Pistons Rotating Assembly

If you're building a serious Pontiac 400 engine for competition, a strong rotating assembly is the heart of your build. This Eagle Competition Rotating Assembly is designed to handle the demands of racing, including applications with nitrous or forced induction. It's a well-built package that gives you the core components needed to create a powerful and reliable engine.

This assembly starts with a forged 4.500-inch crankshaft made from 4340 steel, known for its strength and durability under high stress. Paired with it are 6.800-inch H-beam connecting rods, a popular choice for performance builds due to their robust design. These rods are secured with 7/16-inch ARP 8740 bolts, a trusted name in high-strength fasteners, ensuring they stay tight under extreme loads. The pistons are forged 4032 DSS units with an inverted dome design, measuring 4.160 inches in bore size and featuring a -24cc dish to help achieve your desired compression ratio. They come with plasma-moly file-fit rings, which allow for precise gap setting to optimize performance and sealing. Finally, the assembly includes King XP rod and main bearings, offering excellent wear resistance and smooth operation for the crankshaft.

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