Eagle Chevy 350 1Pc 3.750in Int Balance Crank 5.700in I-Beam Rods 4.060in Pistons Rotating Assembly

If you're building a performance Chevy 350 engine for street and strip use, a balanced rotating assembly is a critical starting point. This assembly from Eagle includes a cast crankshaft, connecting rods, pistons, rings, and bearings, all designed to work together to handle increased power and RPMs. It's a well-built foundation for your project, saving you the time and hassle of sourcing and balancing individual components.

This rotating assembly features a 3.750-inch internal balance cast crankshaft, which is a solid choice for many performance builds. Paired with it are 5.700-inch 5140 I-beam connecting rods, known for their strength and reliability. These rods come equipped with 3/8-inch ARP 8740 bolts, a popular upgrade for ensuring secure rod cap attachment under stress. The pistons are forged 4032 Icon inverted dome units with a -10cc dish, designed for a 4.060-inch bore. They include plasma-moly file-fit rings, allowing for precise ring gap adjustment to suit your specific engine build and tuning. King SI rod and main bearings are also included, providing good wear resistance for street and strip applications.

This assembly is internally balanced, meaning it's designed to work with an automatic transmission or a factory-style external balance flexplate/flywheel. If you're using a manual transmission, you'll need to ensure your flywheel is also internally balanced to match. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's a comprehensive package that gets you well on your way to a powerful and reliable Chevy 350.
