Eagle Chevy 400 3.480in Crank 6.250in H-Beam 6.2cc Dome 4.165in Pistons Rotating Assembly

This Eagle Competition Rotating Assembly gives you a complete package for your Chevy 400 engine build. Inside this kit, you'll find a 3.480-inch forged 4340 crankshaft, ready to handle serious power. It's paired with 6.250-inch H-beam connecting rods, which come equipped with 7/16-inch ARP 2000 bolts for a strong and reliable connection. You also get a set of forged 2618 JE pistons, featuring a 6.2cc dome and a 4.165-inch bore size, along with plasma-moly file-fit piston rings. To finish it off, the assembly includes King XP rod and main bearings, ensuring smooth operation and durability.

This assembly is built for demanding use, including racing applications that might involve nitrous or forced induction. The forged 4340 steel crankshaft and the H-beam connecting rods are well-built to withstand the stresses of high-performance engines. The JE pistons are forged from 2618 aluminum, a material known for its strength and ability to handle high temperatures, and the dome design is specific to the 6.2cc volume. The ARP 2000 bolts are a strong choice for connecting rods, offering excellent clamping force and fatigue resistance. The plasma-moly file-fit rings allow for precise gapping to match your specific cylinder wall and application, which is crucial for optimal sealing and performance. King XP bearings are chosen for their robust construction and ability to maintain oil film under high loads.

When putting this rotating assembly into your Chevy 400, remember that the file-fit piston rings will need to be gapped to your engine's specifications. This is a standard procedure for high-performance builds to ensure proper sealing and prevent ring land damage. This assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. Always refer to the manufacturer's installation instructions for detailed guidance on assembly and setup.
