This Eagle Pro Street rotating assembly gives you the core components needed to rebuild or upgrade your Chevy 400 engine. You'll receive a 3.750-inch forged 4140 crankshaft with 350 main journal size, ready to be paired with your existing block. It also includes a set of 5.700-inch I-beam connecting rods made from strong 4340 steel, which come equipped with 7/16-inch ARP 8740 bolts for secure fastening. The assembly is completed with 4.155-inch forged 4032 Mahle pistons featuring a -5cc flat top design, plasma-moly file-fit piston rings, and King XP rod and main bearings to ensure smooth operation.

This assembly is built for naturally-aspirated racing applications, meaning it's designed to handle the demands of high-RPM operation without forced induction. The use of forged materials for the crankshaft, rods, and pistons signifies a well-built component that offers improved strength and durability over cast alternatives, crucial for performance builds. The ARP bolts are a well-known name for reliability in high-stress engine environments. The included Mahle pistons are a popular choice for their consistent performance and the plasma-moly rings are designed for good sealing and wear resistance. King XP bearings are chosen for their robust construction, suitable for performance engines.

Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's important to verify all dimensions and clearances with your engine block and machine shop before installation to ensure a proper fit and optimal performance for your specific build.
