Eagle Chevy 502 4.250in Crank 6.385in H-Beam 36cc Dome 4.560in Pistons Balanced Assembly

If you're building a high-performance Chevy 502 big block for serious racing, a balanced rotating assembly is the foundation you need. This Eagle Competition Rotating Assembly is designed to handle the demands of competition, including applications using nitrous oxide or forced induction. It’s a complete package that ensures your engine’s internal components are precisely matched for optimal power and durability under extreme stress.

This assembly starts with a forged 4340 steel crankshaft featuring a 4.250-inch stroke, providing the displacement and torque potential for a 502ci engine. Connecting the crank to the pistons are 6.385-inch H-beam connecting rods, known for their strength and reliability in high-RPM applications. These rods are secured with 7/16-inch ARP 8740 bolts, a popular choice for their superior clamping force and resistance to stretching under load. The pistons are forged 4032 aluminum from SRP, featuring a 36cc dome design that contributes to compression ratios suitable for racing, and they measure 4.560 inches in diameter. Topping it off are plasma-moly file-fit piston rings, allowing for precise ring gap adjustment crucial for forced induction or nitrous builds, and King XP rod and main bearings for smooth, durable operation.

This assembly comes balanced from the factory, saving you a significant step and ensuring the internal components are perfectly matched before installation. This is crucial for reducing engine vibration and wear, especially in high-horsepower builds. Keep in mind that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. Always refer to manufacturer installation instructions for proper assembly and break-in procedures.
