Eagle Chevy 327 SJ 3.250in Crank 2.300in Mains 6.125in H-Beam 4.030in Pistons Rotating Assembly

Eagle is well-known for building strong internal engine components, and this Chevy 327 SJ rotating assembly is a prime example of their commitment to performance. If you're building a high-horsepower 327 small journal engine, especially one intended for racing, nitrous, or forced induction, this balanced assembly is designed to handle the stress.

At its core is a 3.250-inch forged 4340 crankshaft, built for durability under demanding conditions. It's paired with 6.125-inch H-beam connecting rods, which are a popular choice for their strength-to-weight ratio. These rods use 7/16-inch ARP 8740 bolts to ensure a secure connection. The assembly includes Mahle forged 4032 pistons with a -5cc flat top dish, sized for a 4.030-inch bore. These pistons come with plasma-moly file-fit rings, giving you the flexibility to set your ring gaps precisely for your application. King XP rod and main bearings are also included, offering robust lubrication and wear resistance for the critical rotating surfaces. This entire package is balanced to work together, simplifying your engine build process.

This rotating assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. Ensure you have the correct machine work done for the 2.300-inch main journals and the 4.030-inch bore. Proper assembly and break-in procedures are crucial for maximizing the lifespan and performance of these components.
