Eagle Chevy 409 Edel 4.000in Crank 6.135in I-Beam Rods .365in 4.342in Pistons Balanced Assembly

If you're building a high-performance naturally-aspirated engine for racing, a balanced rotating assembly is a critical starting point. This Eagle Pro Street assembly is designed for the Chevy 409 engine, providing a solid foundation for serious power. It includes a forged 4340 crankshaft with a 4.000-inch stroke, paired with 6.135-inch 4340 I-beam connecting rods. These rods are equipped with 7/16-inch ARP 8740 bolts, known for their strength and reliability under stress.

The pistons in this assembly are forged 2618 Ross units, measuring 4.342 inches in bore size. They feature a .365-inch Edelbrock dome design, which, when combined with the crankshaft and rod combination, aims for a 10:1 compression ratio. This setup is also supplied with plasma-moly standard gap rings and King XP rod and main bearings, ensuring smooth operation and durability. Having the assembly balanced from the factory saves you significant machine shop time and ensures your engine runs as smoothly as possible.

This rotating assembly is intended for racing applications and is not CARB approved, meaning it cannot be shipped to California. It's a well-built package that takes the guesswork out of matching critical internal engine components for a powerful build.
