If you're building a high-performance Chevy 327 small journal engine, this Eagle Pro Street rotating assembly is a solid foundation. It's designed for naturally-aspirated racing applications, giving you the core components needed to handle increased stress and deliver power reliably.

This assembly starts with a 3.250-inch forged 4340 crankshaft, known for its strength and durability under demanding conditions. The main journals measure 2.300 inches. It's paired with 6.000-inch I-beam connecting rods, which are a popular choice for their balance of strength and weight. These rods come equipped with 3/8-inch ARP 8740 bolts, a well-regarded fastener for ensuring a secure and reliable connection. The pistons are forged 2618 from ICON, featuring a flat-top design with a -4.9cc dish, intended for a 4.030-inch bore. They come with plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing. To complete the package, King XP rod and main bearings are included, offering robust lubrication and wear resistance for the rotating assembly.

This rotating assembly is a significant step up from stock components, providing the internal strength needed for racing builds. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions for proper assembly and tuning of your engine.
