About this part

Product Details

This Eagle Street & Strip rotating assembly gives you the core components needed to rebuild or upgrade your Chrysler 360 engine. Inside this kit, you'll find a 3.580" cast crankshaft, a set of 6.123" I-Beam connecting rods equipped with 3/8" ARP 8740 bolts, hypereutectic KB pistons with a -25cc inverted dome designed for a 4.040" bore, plasma-moly file-fit piston rings, and King rod and main bearings. This assembly is specifically put together for pump gas, naturally aspirated street applications, making it a solid choice for many rebuild projects.

The I-Beam connecting rods are well-built for street use, and the inclusion of ARP 8740 bolts means you're getting strong, reliable fasteners for the rods. The KB pistons feature an inverted dome design, which is a notable detail for managing compression in a naturally aspirated setup. These pistons are paired with plasma-moly file-fit rings, giving you the flexibility to achieve a precise fit in the cylinder bore for improved sealing and performance. The King bearings are a popular choice for their durability and smooth operation, ensuring the crankshaft spins freely and reliably.

This rotating assembly is intended for use with pump gas and naturally aspirated engines, meaning it's designed to work well without forced induction or exotic fuels. It's important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. When planning your build, ensure you have all the necessary supporting components, such as gaskets, seals, and oil, to complete the engine assembly process.
