Eagle Chevrolet Small Block 5.7L V8 Balanced Rotating Assembly Kit 4.030in Bore 3.750in Stroke

If you're rebuilding the heart of your Chevrolet 350 engine for serious performance, a balanced rotating assembly is where you start. This kit from Eagle takes the guesswork out of matching critical components, ensuring your V8 runs smoothly and reliably under demanding conditions, whether you're on the track or pushing the limits on the street. It's designed to handle the extra stress that comes with racing, including nitrous and forced induction setups.

Inside this kit, you'll find a forged 4340 steel crankshaft with a 3.750-inch stroke, ready to deliver more displacement and power. Paired with it are 6.000-inch H-beam connecting rods, known for their strength and durability, secured with 7/16-inch ARP 8740 bolts. The pistons are forged 4032 aluminum with a -16cc inverted dome design, specifically for a 4.030-inch bore, and come with plasma-moly file-fit rings. This combination is precision balanced to reduce vibration and improve overall engine life. For the bearings, Eagle has included King XP rod and main bearings, offering robust protection for these high-stress components.

This balanced rotating assembly is a solid foundation for a high-performance engine build. 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 torque specifications.
