About this part

Product Details

This Eagle Competition Rotating Assembly is built around a 3.250-inch forged 4340 steel crankshaft, a material known for its strength and durability under high stress. It's designed for the Chevy 327 small journal engine, and the crankshaft features 2.300-inch main journals, which are smaller than standard big journal cranks, requiring specific bearings and machine work. This assembly is intended for serious performance applications, including those using nitrous oxide or forced induction, where robust internal engine components are essential.

The assembly includes 6.000-inch H-beam connecting rods, which offer a strong and reliable link between the piston and crankshaft. These rods are equipped with 7/16-inch ARP 8740 bolts, a popular choice for their strength and ability to handle significant cylinder pressures. Paired with the rods are forged 2618 aluminum pistons from ICON, featuring a -4.9cc flat top design and a 4.030-inch bore size, suitable for achieving a desired compression ratio when combined with your cylinder heads. The pistons come with plasma-moly file-fit rings, allowing for precise gap adjustment to match your engine's specific bore and intended use, which is crucial for optimal sealing and performance. King XP rod and main bearings are also included, offering advanced bearing technology for reduced friction and improved longevity.

This is a comprehensive rotating assembly intended for builders who need a solid foundation for a high-performance or racing engine. Please note that this assembly is not CARB approved and cannot be shipped to California. It's important to consult with your engine builder or machinist to ensure all components are compatible with your specific build plans and that any necessary machine work is performed correctly.
