Eagle Chevy 350 1Pc 3.750in Crank 6.000in H-Beam -5cc Flat Top 4.040in Pistons Balanced Assembly

If you're building a high-performance Chevy 350 engine for racing, especially with nitrous or forced induction, a balanced rotating assembly is a critical starting point. This assembly from Eagle is designed to handle the stresses of competition, providing a solid foundation for your build.

At its heart is a 3.750-inch forged 4340 crankshaft, known for its strength and durability under extreme loads. Paired with this are 6.000-inch H-beam connecting rods, which are a popular choice for their robust design. These rods are secured with 7/16-inch ARP 8740 bolts, a name trusted for their reliability in high-stress applications. The pistons are forged 4032 aluminum from Icon, featuring a -5cc flat top design that works well with various cylinder head combinations, and they come with plasma-moly file-fit rings. To ensure smooth operation and longevity, the assembly includes King XP rod and main bearings, which are well-regarded for their performance in demanding conditions.

This assembly comes balanced from the factory, saving you a significant step and ensuring proper weight distribution for reduced vibration and improved engine life. 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.
