Eagle Chevy 350 3.750in Crank 5.700in H-Beam -5cc Flat Top 4.040in Pistons Balanced Assembly

If you're building a high-performance Chevy 350 for serious racing, a balanced rotating assembly like this one from Eagle is a critical starting point. This assembly includes a forged 4340 crankshaft with a 3.750-inch stroke, H-beam connecting rods that are 5.700 inches long, and Icon forged pistons with a -5cc flat top dish. It's all balanced together, which is essential for smooth operation and longevity at high RPMs.

The H-beam connecting rods are strong and come with 7/16-inch ARP 8740 bolts, a solid choice for handling the stresses of racing, including nitrous or forced induction applications. The Icon pistons are made from forged 4032 aluminum, known for its good thermal expansion properties, and they feature a flat top design with a -5cc dish, which will affect your compression ratio depending on your cylinder heads. This assembly also includes plasma-moly file-fit piston rings and King XP rod and main bearings, so you're getting well-regarded components for the rotating assembly.

Because this assembly is balanced, it significantly simplifies your engine build process. It's designed for competition use, so it's not CARB approved and cannot be shipped to California. Remember to consult your engine builder or machine shop for specific installation requirements and to ensure all clearances are correct for your particular build.
