This Eagle Street & Strip rotating assembly gives you the core components to rebuild or upgrade your Pontiac 400 engine. Inside this kit, you'll find a 4.250-inch cast crankshaft, a set of 6.800-inch I-beam connecting rods equipped with 7/16-inch ARP 8740 bolts, and forged 4032 Mahle pistons. These pistons are a -6cc flat top design and come with plasma-moly file-fit rings, ready for your build. The assembly also includes King SI rod and main bearings to ensure proper lubrication and support for the rotating assembly.

This rotating assembly is specifically designed for street vehicles running on pump gas and intended for naturally aspirated applications. The forged Mahle pistons are a solid choice for their durability and performance on the street, and the inclusion of ARP bolts in the connecting rods means you're getting strong, reliable fasteners. The plasma-moly rings are designed for good sealing and wear characteristics. This is a well-built package aimed at providing a strong foundation for your Pontiac 400 build, whether you're restoring an old favorite or looking for more reliable power.

When installing this rotating assembly, remember that it's intended for naturally aspirated, pump gas street use. It's important to follow proper engine building procedures, including checking clearances and ensuring correct assembly torque specifications are met. This kit provides the essential rotating components, so you'll need to source other necessary engine parts like gaskets, seals, and potentially an oil pump and timing set to complete your engine build.
