If you're building a street-driven Chevy 400 engine that will run on pump gas and doesn't use a power adder, this Eagle Street & Strip rotating assembly is a solid foundation. It's a complete, balanced package designed to get your project off the ground with reliable components.

This assembly includes a 3.750-inch cast crankshaft and 5.700-inch I-beam connecting rods, which are a common and well-regarded combination for Chevy 400 builds. The rods are secured with 3/8-inch ARP 8740 bolts, known for their strength and reliability in performance applications. Forged 4032 aluminum pistons from ICON are included, featuring an inverted dome design with a -23cc volume and a 4.165-inch bore size, paired with plasma-moly file-fit piston rings. This setup is balanced as a complete assembly, which is a critical step for smooth engine operation and longevity. You'll also find King rod and main bearings, a damper, and a flexplate in the box, making this a comprehensive rotating assembly kit.

Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's important to check all manufacturer instructions for proper installation and assembly procedures to ensure the best performance and durability from your new engine components.
