About this part

Product Details

If you're building a high-performance Chevy 327 engine, this Eagle Competition Rotating Assembly is a solid foundation. It includes a forged 4340 crankshaft with a 3.250-inch stroke, H-beam connecting rods that are 6.125 inches long, and forged 4032 Mahle pistons with an 11.1cc dome and a 4.040-inch bore size. This assembly is designed to handle the demands of racing, including applications using nitrous oxide or forced induction.

The forged 4340 steel crankshaft offers improved strength and durability over cast cranks, making it well-suited for higher RPMs and increased stress. The 6.125-inch H-beam connecting rods are known for their robust design and are paired with 7/16-inch ARP 8740 bolts, ensuring a strong connection between the crank and pistons. The Mahle pistons are forged from 4032 aluminum, which offers good thermal expansion properties for a tighter piston-to-wall clearance, and they come with plasma-moly file-fit rings. King XP rod and main bearings are included, providing reliable lubrication and reduced friction for the rotating assembly.

This rotating assembly is a comprehensive package for serious engine builders. Please note that this assembly is not CARB approved and cannot be shipped to California. It's important to consult your engine builder or refer to manufacturer specifications for proper installation and balancing procedures, as rotating assemblies typically require balancing to the specific vehicle and application.
