Eagle Chevy 454 4.000in Crank 6.135in I-Beam Rods 27cc Dome 4.350in Pistons Rotating Assembly

This Eagle Pro Street Rotating Assembly is built for Chevy 454 engines, specifically for naturally-aspirated racing applications. What you get in this kit is a complete package designed to form the heart of your engine build. It includes a 4.000-inch forged 4340 crankshaft, a set of 6.135-inch 4340 I-beam connecting rods fitted with 7/16-inch ARP 8740 bolts, and forged 2618 ICON pistons. These pistons feature a 27cc closed chamber dome design and measure 4.350 inches in diameter. The assembly also comes with plasma-moly file-fit piston rings and King XP rod and main bearings, ensuring a well-matched set for performance.

The choice of materials here is key for durability under racing conditions. The forged 4340 steel for both the crankshaft and connecting rods offers a strong foundation, significantly more robust than cast components. The ARP bolts used on the connecting rods are well-known for their reliability and ability to maintain clamping force under high stress. ICON pistons are a popular choice for performance builds, and the 27cc dome shape is designed to work with specific compression ratios in naturally-aspirated setups. The plasma-moly file-fit rings allow for precise gap setting to match your engine's bore and intended use, which is crucial for sealing and performance. Finally, the King XP bearings are engineered for high-load applications, providing the necessary lubrication and wear resistance for the crankshaft and connecting rod journals.

This rotating assembly is a substantial upgrade for anyone building a performance 454. It's important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. You'll want to ensure you have all the necessary supporting components for your engine build, such as camshafts, cylinder heads, and a proper block preparation, to take full advantage of this high-performance rotating assembly.
