Product Details
This Eagle Competition Rotating Assembly starts with a forged 4340 steel crankshaft featuring a 3.480-inch stroke. This is a crucial component for building a strong Chevy 350 engine, especially when you're pushing the limits with racing, nitrous, or forced induction. The forged construction means it can handle significantly more stress than a cast crank, making it a solid choice for high-performance applications.
Paired with the crank are 5.700-inch H-beam connecting rods. These rods are known for their strength and are secured with 7/16-inch ARP 8740 bolts, a name you can trust for reliable clamping force under extreme conditions. The assembly also includes 4.030-inch SRP forged pistons with an inverted dome design, offering -24cc volume to help achieve your desired compression ratio. These pistons are made from 4032 aluminum, which offers good thermal expansion properties for a tighter piston-to-wall clearance. They come with plasma-moly file-fit rings, allowing you to precisely set the ring gap for your specific application, and King XP series rod and main bearings are included to ensure smooth rotation and proper oil clearance.
This assembly comes balanced from Eagle, saving you a significant step and ensuring the rotating mass is properly weighted. This is essential for engine longevity and smooth operation, especially at higher RPMs. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's designed for serious performance builds where durability and strength are paramount.
