Product Details
This Eagle Competition Rotating Assembly is a complete package designed for serious performance builds, especially those involving racing, nitrous, or forced induction. What you get in this kit is a 3.875-inch forged 4340 crankshaft, 6.000-inch H-beam stroker clearance connecting rods, and 4.125-inch forged Mahle pistons with an inverted dome design that displaces 22cc. It also includes plasma-moly file-fit piston rings and King XP rod and main bearings, along with 7/16-inch ARP 2000 bolts for the connecting rods.
The components in this assembly are built for demanding use. The forged 4340 steel crankshaft offers a strong foundation, while the H-beam connecting rods are specifically designed with extra clearance for stroker applications, ensuring they can handle the increased travel. The Mahle pistons are forged from 4032 aluminum, known for its strength and thermal expansion properties, and feature an inverted dome to achieve the desired compression ratio with the included components. The ARP 2000 bolts are a well-known upgrade for connecting rod security under high stress.
This rotating assembly is a significant step up for a Chevy 400 engine aiming for higher performance levels. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always consult the manufacturer's installation guide for proper assembly and torque specifications to ensure optimal performance and longevity.
