Eagle Chrysler 340 4.000in Crank 6.123in I-Beam Rods -5cc Flat Top 4.040in Pistons Rotating Assembly

This Eagle Street & Strip rotating assembly gives you the core components to rebuild or upgrade your Chrysler 340 engine. Inside this kit, you'll find a 4.000-inch cast crankshaft, a set of 6.123-inch I-beam connecting rods equipped with 3/8-inch ARP 8740 bolts, and forged 2618 Mahle pistons. These pistons are a -5cc flat top design and are sized for a 4.040-inch bore. The assembly also includes plasma-moly file-fit piston rings and King SI rod and main bearings, so you have the essential pieces to get your short block assembled.

This rotating assembly is specifically put together for street applications running on pump gas and in naturally aspirated configurations. The cast crank is a solid choice for street use, offering good durability for everyday driving. The I-beam rods are well-built and paired with ARP bolts, which are known for their strength and reliability under stress. Mahle pistons are a popular choice for their consistent quality and performance, and the flat top design with a -5cc dish is a common setup for many 340 builds, helping to achieve a good compression ratio with various cylinder heads. The included file-fit rings allow for precise gapping to match your specific engine build and desired piston-to-wall clearance, which is important for proper sealing and oil control.

When assembling this rotating assembly, remember that the piston rings are file-fit, meaning you'll need to gap them to your engine's specifications. This is a standard procedure for performance engine builds and ensures optimal ring seal. This assembly is intended for street use and is not CARB approved, so it cannot be shipped to California. Always refer to the manufacturer's detailed instructions for proper installation and assembly procedures.
