About this part

Product Details

This Eagle Pro Street rotating assembly gives you the core components to rebuild or upgrade your Chrysler 340 engine for naturally-aspirated racing applications. Inside this kit, you'll find a 3.310-inch forged 4340 crankshaft, built to handle the stresses of performance use. Paired with the crank are 6.123-inch I-beam connecting rods, which come equipped with 3/8-inch ARP 8740 bolts for a strong and secure connection.

The assembly also includes KB hyper eutectic flat-top pistons designed for a -6cc combustion chamber volume, with a 4.100-inch bore size. These pistons are matched with plasma-moly file-fit piston rings, allowing for precise ring gap adjustment during installation. To complete the rotating assembly, King XP rod and main bearings are included, offering reliable lubrication and reduced friction for critical engine components.

This kit is intended for naturally-aspirated racing builds and is not CARB approved, meaning it cannot be shipped to California. Please refer to the manufacturer's installation instructions for proper assembly and tuning procedures.
