If you're rebuilding a Chevy 350 engine for street use, especially for a naturally aspirated setup on pump gas, a balanced rotating assembly like this one from Eagle is a solid foundation. It bundles together the core components that spin inside your engine, all balanced as a set to ensure smooth operation and reduce vibration.

This assembly starts with a 3.750-inch cast crankshaft, paired with 5.700-inch I-beam connecting rods. These rods are secured with 3/8-inch ARP 8740 bolts, known for their strength and reliability. The pistons are forged 4032 aluminum from ICON, featuring a -5cc flat top design and a 4.060-inch bore size, ready for plasma-moly standard gap rings. To complete the package, it includes King SI rod and main bearings, a damper, and a 168-tooth flexplate, all balanced from the factory. This means you get a matched set of critical internal components ready to be installed.

This assembly is specifically designed for street applications and is suitable for naturally aspirated engines running on pump gas. It's important to note that this part 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.
