Eagle Chevy 454 4.000in Crank 6.135in H-Beam -3cc Flat Top 4.320in Pistons Balanced Assembly

If you're building a high-performance Chevy 454 engine for serious racing, a balanced rotating assembly like this one from Eagle is a critical starting point. This assembly bundles together the core components that spin inside your engine's crankcase, ensuring they work together harmoniously for maximum power and durability under demanding conditions. It's designed to handle the stresses of racing, including nitrous and forced induction applications.

Eagle has put together a well-built package here. You get a 4.000-inch forged 4340 steel crankshaft, known for its strength and reliability. Paired with it are 6.135-inch H-beam connecting rods, which are a popular choice for their robust design, secured with 7/16-inch ARP 8740 bolts. The pistons are forged 4032 aluminum from Icon, featuring a -3cc flat top design and a 4.320-inch bore size, ready for your specific ring gap setup with the included plasma-moly file-fit rings. To top it off, King XP rod and main bearings are included, offering excellent wear resistance and performance.

This assembly comes balanced from Eagle, saving you a significant step and ensuring the rotating mass is properly weighted. This is crucial for reducing engine vibration and improving overall longevity, especially when you're pushing the engine hard. 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.
