About this part

Product Details

If you're rebuilding the heart of your Chrysler 360 for serious naturally-aspirated racing, this Eagle Pro Street rotating assembly is a solid foundation. It bundles together the essential rotating components, all balanced and ready to go, saving you time and ensuring compatibility between parts.

This assembly starts with a 3.580-inch forged 4340 crankshaft, known for its strength and durability under high stress. Paired with it are 6.123-inch I-beam connecting rods, which are a popular choice for their balance of strength and weight. These rods come equipped with 3/8-inch ARP 8740 bolts, a well-known name for reliable fasteners that hold tight under extreme conditions. The pistons are hypereutectic KB units with an inverted dome design, creating an -18cc volume to help achieve a specific compression ratio, and they're sized for a 4.040-inch bore. The assembly also includes plasma-moly file-fit piston rings, giving you the flexibility to set the correct ring gap for your application, and King XP rod and main bearings to ensure smooth rotation and proper oil clearance.

This is a comprehensive package designed for performance builds. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to get the most out of these components.
