Eagle Chevy 327 SJ 3.250in Crank 2.300in Mains 5.700in H-Beam 4.030in Pistons Rotating Assembly

This Eagle Chevy 327 SJ rotating assembly gives you the core components to rebuild or upgrade your engine. Inside this package, you'll find a 3.250-inch forged 4340 crankshaft, a set of 5.700-inch H-beam connecting rods fitted with 7/16-inch ARP 8740 bolts, and 4.030-inch forged 2618 Icon pistons. It also includes plasma-moly file-fit piston rings and King XP rod and main bearings to complete the assembly.

This is a well-built setup designed for demanding use, including racing applications that might involve nitrous or forced induction. The forged 4340 steel crankshaft is strong and durable, ready to handle increased stress. The H-beam connecting rods are a popular choice for their strength-to-weight ratio, and the inclusion of ARP bolts means you're getting reliable hardware for securing the rods. The Icon pistons are forged from 2618 aluminum, a material known for its expansion characteristics under high heat, and they feature a -4.9cc flat top dish. The plasma-moly file-fit rings allow for precise gapping to match your specific cylinder wall finish and bore size, which is crucial for proper sealing and performance. King XP bearings are known for their robust construction and ability to handle heavy loads.

This assembly is specifically for the Chevy 327 Small Journal (S.J.) engine, featuring 2.300-inch main journals on the crankshaft. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and assembly procedures.
