Eagle Chevy 327 SJ 3.250in Crank 2.300in Main 6.000in H-Beam 6.3cc 4.000in Pistons Rotating Assembly

This Eagle Competition Rotating Assembly starts with a 3.250-inch forged 4340 crankshaft, designed for the demands of racing, including nitrous and forced induction applications. It features 2.300-inch main journals, a critical measurement for engine builders seeking specific clearances and oil pressure characteristics. The assembly is built around 6.000-inch H-beam connecting rods, known for their strength and reliability under high stress. These rods are secured with 7/16-inch ARP 8740 bolts, a popular choice for their durability and consistent clamping force, ensuring the rods stay firmly attached even under extreme loads.

The included pistons are forged 2618 aluminum from ICON, featuring a 6.3cc dome volume and a 4.000-inch bore size. These pistons are paired with plasma-moly file-fit rings, allowing for precise gap setting to match your specific engine build and optimize sealing. To complete the rotating assembly, King XP rod and main bearings are included. These bearings offer enhanced performance and durability, crucial for maintaining oil film and reducing friction in a high-performance engine. This comprehensive package is engineered for serious competition builds.
