Eagle Chevy 350 3.750in Crank 5.700in H-Beam -5cc Flat Top 4.000in Pistons Balanced Assembly

If you're building a high-performance Chevy 350 engine, especially for racing applications, this balanced rotating assembly from Eagle is a solid foundation. It's designed to handle the demands of competition, including the extra stress from nitrous or forced induction setups. This assembly includes all the key components you need to get your engine rotating reliably.

At the heart of this assembly is a forged 4340 crankshaft with a 3.750-inch stroke, paired with 5.700-inch H-beam connecting rods. These rods are secured with 7/16-inch ARP 8740 bolts, known for their strength and reliability under high loads. The pistons are forged 4032 aluminum from ICON, featuring a -5cc flat-top design with a 4.000-inch bore, suitable for various compression ratio targets. To ensure proper ring seal and performance, it comes with plasma-moly file-fit rings, meaning you can adjust them for a perfect fit in your cylinders. This assembly also includes King XP rod and main bearings, which offer improved durability and performance for demanding use.

This is a balanced assembly, meaning the crankshaft, rods, pistons, rings, and bearings have been pre-balanced at the factory to reduce engine vibration and stress on your main bearings. This saves you a significant step in the engine building process. Please note that this assembly is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
