About this part

Product Details

If you're building a high-performance Chevy 400 engine for serious racing, a strong rotating assembly is the heart of the operation. This Eagle Competition Rotating Assembly is designed to handle the demands of competition, whether you're running nitrous or forced induction. 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 3.750-inch forged 4340 crankshaft, known for its strength and durability under stress. Paired with this are 5.700-inch H-beam connecting rods, also forged from 4340 steel, and secured with 7/16-inch ARP 8740 bolts. These rods are a popular choice for performance builds because they offer a solid balance of strength and weight. The kit includes forged 4032 DSS pistons with an inverted dome design, featuring a -16cc volume and a 4.165-inch bore size. These pistons are designed to work with the included plasma-moly file-fit rings, which allow for precise gap setting to match your engine's specific needs. To top it off, King XP rod and main bearings are included, providing excellent lubrication and wear resistance for critical rotating components.

This assembly is a significant step up from stock components, offering the robustness required for racing applications. Remember that this assembly is not CARB approved and cannot be shipped to California. It's crucial to follow all manufacturer installation guidelines and torque specifications when assembling your engine to ensure optimal performance and longevity.
