Eagle Chevy 327 SJ 3.250in Crank 2.300in Mains 6.000in I-Beam Rods 4.000in Pistons Rotating Assembly

This is the Eagle Chevy 327 SJ Pro Street Rotating Assembly, a complete package designed for your small-journal 327 engine. If you're building a naturally-aspirated racing engine or a high-performance street machine that demands robust internals, this assembly is a solid foundation. It brings together all the critical rotating components you need to get your engine project moving forward.

At the heart of this assembly is a 3.250-inch forged 4340 crankshaft, known for its strength and durability under demanding conditions. The mains measure 2.300 inches, specific to the small journal configuration. Paired with the crank are 6.000-inch I-beam connecting rods, which are secured with 3/8-inch ARP 8740 bolts, a popular choice for their reliability and clamping force. The pistons are forged 4.000-inch ICON units, made from 2618 aluminum for good thermal stability, and feature a 6.3cc dome to help achieve your desired compression ratio. This assembly also includes plasma-moly file-fit piston rings and King XP rod and main bearings, ensuring proper clearances and lubrication right out of the box.

This rotating assembly is intended for racing applications and is not CARB approved, meaning it cannot be shipped to California. It's a well-built package that consolidates many of the essential internal engine components, simplifying your build process. Ensure you have the proper machine work done to your block to accommodate these components, and always follow manufacturer guidelines for assembly and break-in procedures.
