About this part

Product Details

Eagle is well-known for making strong internal engine components, and this balanced rotating assembly is a prime example of their commitment to performance. This assembly is built for Chevy 350 engines and is designed to handle the demands of racing, including the stress from nitrous and forced induction setups. It's a complete package that gives you a solid foundation for a high-horsepower build.

At the heart of this assembly is a forged 4340 crankshaft with a 3.875-inch stroke, which is larger than stock to increase displacement and power potential. Paired with this are 6.000-inch H-beam connecting rods, known for their strength and ability to clear the larger stroker crank. These rods come with 7/16-inch ARP 2000 bolts, a popular choice for their reliability under high stress. The pistons are forged 4032 aluminum from Mahle, featuring a -5cc flat top design that works well with various cylinder head combinations and a 4.040-inch bore size. They also include plasma-moly file-fit rings, allowing you to precisely gap them for your specific engine build, and King XP rod and main bearings are included to ensure smooth rotation and durability.

This assembly comes balanced from the factory, saving you a significant step and cost in your engine build process. It's important to note that this part is not CARB approved and cannot be shipped to California due to emissions regulations. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
