Product Details
If you're building a high-performance Chevy 327 engine for serious competition, a strong rotating assembly is the heart of the operation. This Eagle Competition Rotating Assembly is designed to handle the demands of racing, including the extra stress from nitrous or forced induction setups. It's a well-built package that gives you the core components needed to create a powerful and reliable engine.
At the center of this assembly is a 3.000-inch forged 4340 crankshaft, known for its strength and durability under high loads. Paired with this are 6.125-inch H-beam connecting rods, which are a popular choice for performance builds due to their robust design and ability to withstand significant stress. These rods use 7/16-inch ARP 8740 bolts, a name you can trust for secure and reliable connections. The pistons are forged ICON 4032 aluminum flat tops, measuring 4.040 inches in bore size and featuring a -4.9cc dish to help achieve your desired compression ratio. The assembly also includes plasma-moly file-fit piston rings, which allow for precise ring gap setting to optimize performance and sealing. Finally, King XP rod and main bearings are included, offering excellent wear resistance and smooth operation for the crankshaft.
This rotating assembly is a solid foundation for a performance 327 build. 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 to ensure optimal performance and longevity of your new engine components.
