Product Details
If you're rebuilding the heart of your Chevy 350 for serious performance, a balanced rotating assembly like this one from Eagle is a critical step. This assembly includes a forged 4340 crankshaft with a 3.750-inch stroke, paired with 5.700-inch H-beam connecting rods secured by 7/16-inch ARP 8740 bolts. These components are built to handle the stresses of high-RPM operation and increased cylinder pressures, making them suitable for racing applications, including those using nitrous or forced induction.
The assembly also features forged 4032 Icon pistons with a -5cc flat top design, intended for a 4.040-inch bore. These pistons are matched with plasma-moly file-fit rings, which allow for precise gap setting to optimize sealing and performance. To ensure smooth operation and durability, King XP rod and main bearings are included. This balanced assembly is designed to reduce vibration and improve overall engine balance, which is essential for longevity and power delivery in demanding builds.
This rotating assembly is a well-built foundation for a performance engine. Please note that this assembly is not CARB approved and cannot be shipped to California. It's important to consult with your engine builder or refer to Eagle's specific installation guidelines for proper assembly and break-in procedures to ensure optimal performance and reliability.
