Product Details
Eagle is well-known for making strong internal engine components, and this rotating assembly is a prime example of their commitment to performance. If you're building a Chevy 350 for serious street or strip duty, this package gives you the core components needed to handle increased power and stress. It includes a forged crankshaft, connecting rods, pistons, rings, and bearings, all designed to work together as a balanced unit.
The heart of this assembly is a 3.750-inch forged 4340 steel crankshaft, chosen for its strength and durability under high loads. Paired with it are 6.000-inch H-beam connecting rods, which are also forged from 4340 steel and secured with 7/16-inch ARP 8740 bolts. These rods are a popular choice for their robust design, capable of handling significant horsepower. The pistons are forged 4032 aluminum from Icon, featuring an inverted dome design with -18cc volume and a 4.040-inch bore size. They come with plasma-moly file-fit rings, meaning you can adjust the ring gap for your specific application, which is crucial for optimal performance and sealing, especially with forced induction or nitrous. King XP rod and main bearings are included to ensure smooth rotation and proper oil clearance.
This assembly is intended for competition use, including applications with nitrous and forced induction. Please note that this part is not CARB approved and cannot be shipped to California. It's important to consult with your engine builder or refer to manufacturer instructions for proper installation and balancing procedures, as these components are critical to the longevity and performance of your engine.
