Product Details
If you're rebuilding a Chevy 350 engine for serious performance, a strong rotating assembly is the heart of the build. This Eagle Competition Rotating Assembly is designed to handle the demands of racing, including nitrous and forced induction setups. It gives you the core components needed to build a powerful and reliable engine.
This assembly starts with a forged 4340 steel crankshaft featuring a 3.750-inch stroke, providing a good balance for many performance applications. Paired with the crank are 5.700-inch H-beam connecting rods, known for their strength and ability to withstand high RPMs and significant cylinder pressures. These rods use 7/16-inch ARP 8740 bolts, a popular choice for their reliability in performance engines. The pistons are forged 4032 aluminum from ICON, featuring a -5cc flat top design that works well with various compression ratios, especially when aiming for forced induction or nitrous. They come with plasma-moly file-fit rings, allowing for precise gap setting to match your specific application and ensure good sealing. To complete the package, King XP rod and main bearings are included, offering robust performance for demanding use.
This is a comprehensive rotating assembly, but remember that it's not CARB approved and cannot be shipped to California. For optimal results, always refer to the manufacturer's installation instructions and ensure all components are properly balanced and clearanced for your specific engine build.
