About this part

Product Details

This Eagle rotating assembly is built around a 3.000-inch forged 4340 crankshaft, a solid foundation for a high-performance Chevy 327 build. The crankshaft's forged 4340 steel construction means it can handle the stresses of demanding engine use, including racing applications with nitrous or forced induction. This assembly is designed to be a complete package, giving you the core components needed to rebuild or upgrade your engine's bottom end.

Complementing the crankshaft are 6.125-inch H-beam connecting rods, known for their strength and ability to withstand high RPMs and significant cylinder pressures. These rods are secured with 7/16-inch ARP 8740 bolts, a well-regarded choice for their reliability in performance applications. The pistons are forged 4032 ICON units, featuring a -4.9cc flat top design and a 4.030-inch bore size, which are crucial for achieving the desired compression ratio with your chosen cylinder heads. They come with plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing. King XP rod and main bearings are included, offering robust lubrication and wear resistance for the rotating assembly.

This assembly is a popular choice for racers and serious engine builders looking for a well-built rotating assembly that can be pushed hard. Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and assembly procedures.
