This Eagle Pro Street rotating assembly gives you the core components to rebuild or upgrade your Chevy 400 engine. Inside this package, you'll find a 3.750-inch forged 4140 crankshaft designed for 350 main journal sizes. It's paired with 5.700-inch I-beam connecting rods made from strong 4340 steel, which come equipped with 7/16-inch ARP 8740 bolts for a secure connection. The assembly also includes forged 4032 Icon pistons with a -5cc flat top dish, measuring 4.185 inches in diameter. To complete the rotating assembly, you get plasma-moly file-fit piston rings and King XP rod and main bearings.

This assembly is built for naturally-aspirated racing applications, meaning it's intended for engines that don't use a turbocharger or supercharger. The use of forged materials for the crankshaft, rods, and pistons indicates a well-built component designed to handle the stresses of performance use. The Icon pistons are a popular choice for their durability and compatibility with performance builds. The inclusion of ARP bolts means you're getting hardware known for its strength and reliability. The file-fit rings offer flexibility for precise installation, allowing a mechanic to achieve optimal piston-to-wall clearance. King XP bearings are also a well-regarded option for performance engines, offering good load capacity and durability.

When installing this rotating assembly, it's important to follow proper engine building procedures, including meticulous cleaning, balancing, and lubrication. Refer to the manufacturer's detailed installation instructions for specific guidance on clearances and assembly. Please note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations.
