Eagle Chevy 427/454 3.766in Crank 6.135in I-Beam Rods 4.250in Pistons Rotating Assembly

This Eagle Pro Street rotating assembly gives you the core components to rebuild or upgrade the heart of your Chevy 427 or 454 engine. You get a 3.766-inch forged 4340 crankshaft, 6.135-inch 4340 I-beam connecting rods fitted with 7/16-inch ARP 8740 bolts, and forged 4032 Wiseco ProTru 21cc dome pistons. It also includes plasma-moly file-fit piston rings and King XP rod and main bearings to get you started.

This assembly is built for naturally-aspirated racing applications, meaning it’s designed to handle the demands of high-RPM operation without forced induction. The forged 4340 steel used for both the crankshaft and connecting rods offers a strong foundation, providing durability and reliability under stress. The Wiseco pistons are forged from 4032 aluminum, a material known for its strength and thermal expansion properties, which helps maintain piston-to-wall clearance as temperatures rise. The included ARP bolts are a well-known name in high-performance engine fasteners, ensuring a secure connection between the rod and crankshaft. The plasma-moly rings are designed for good sealing and durability, and the King XP bearings are engineered for high-performance lubrication needs.

This is a comprehensive rotating assembly, but remember that it's not CARB approved and cannot be shipped to California. You'll need to source other necessary components like your camshaft, cylinder heads, and oil pump separately to complete your engine build. Refer to the manufacturer's installation instructions for specific assembly and torque specifications.
