Eagle Chevy 350 1Pc 3.750in Crank 5.700in I-Beam Rods -18cc 4.060in Pistons Balanced Assembly

If you're building a high-performance Chevy 350 for naturally-aspirated racing, a balanced rotating assembly is a critical starting point. This Pro Street assembly from Eagle is designed to handle the demands of the track, providing a solid foundation for your engine build. It includes all the key components you need to get your short block assembled and ready for the rest of your build.

Eagle starts with a strong 3.750-inch forged 4140 crankshaft, paired with 5.700-inch I-beam connecting rods made from durable 4340 steel. These rods are secured with robust 7/16-inch ARP 8740 bolts, ensuring they stay put under stress. The assembly also features 4.060-inch forged 4132 Icon pistons with an -18cc inverted dome, designed to work with specific compression ratios. To ensure proper ring seal and longevity, it comes with plasma-moly file-fit rings and King XP rod and main bearings.

This assembly is balanced from the factory, which is a crucial step for engine longevity and smooth operation, especially at higher RPMs. Having the rotating assembly balanced as a complete unit helps reduce vibration and stress on your engine's internal components. Please note that this assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder or manufacturer's specifications for installation details and any additional components required for your specific application.
