Eagle Chevy 454 4.000in Crank 6.135in I-Beam Rods 43cc Dome 4.250in Pistons Balanced Assembly

If you're building a naturally-aspirated 454 big block Chevy for racing, a balanced rotating assembly like this one from Eagle is a solid foundation. It bundles together the core components you need to get your engine rotating, all balanced as a set to ensure smooth operation and reduce vibration at higher RPMs. This assembly is designed to handle the demands of the track, providing a strong starting point for your performance build.

This Eagle Pro Street assembly includes a forged 4340 steel crankshaft with a 4.000-inch stroke, paired with 6.135-inch long I-beam connecting rods made from the same durable 4340 material. The rods are secured with 7/16-inch ARP 8740 bolts, known for their strength and reliability under stress. For the pistons, you get forged 2618 aluminum units from ICON, featuring a 43cc dome and a 4.250-inch bore size, which are designed to work with plasma-moly file-fit rings. To complete the rotating assembly, King XP series rod and main bearings are included, offering excellent wear resistance and performance.

Because this is a balanced assembly, it saves you a significant step in the engine building process, ensuring the crankshaft, rods, pistons, rings, and bearings are precisely weighted and balanced together. This is crucial for high-performance engines to minimize internal stress and maximize power output. Please note that this assembly is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
