About this part

Product Details

If you're building or rebuilding a Chevy 350 engine for street use, this balanced rotating assembly from Eagle is a solid choice. It includes a 3.750-inch cast crankshaft, 5.700-inch I-beam connecting rods with ARP 8740 bolts, hypereutectic KB flat-top pistons with a -7cc dish, plasma-moly standard gap rings, and King SI rod and main bearings. This assembly is balanced and ready to go for pump gas, naturally aspirated street applications.

Eagle has put together a well-built package here that takes the guesswork out of matching components for your small-block Chevy. The cast crankshaft is a durable option for street performance, and the I-beam rods are strong enough for many street builds, especially when paired with the included ARP 8740 bolts. The hypereutectic pistons are a good choice for pump gas applications, and the -7cc dish helps achieve a reasonable compression ratio for street driving. Plasma-moly rings are known for their good sealing and durability in these types of applications. Everything comes balanced from the factory, saving you a significant machining step and cost.

This assembly is designed for naturally aspirated, pump gas street vehicles. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer installation instructions for proper assembly and break-in procedures.
