Product Details
This Eagle Competition Rotating Assembly is built around a forged 4340 steel crankshaft with a 3.875-inch stroke, designed to work with 350 mains in a Chevy 400 block. This is a serious piece for anyone looking to build a high-performance engine, especially for racing applications where nitrous or forced induction might be involved. The crankshaft is the heart of the assembly, and using a forged 4340 steel construction means it can handle significant stress and power output.
Complementing the crank are 6.000-inch H-beam stroker rods. These rods are specifically designed with extra clearance for stroker applications and feature 7/16-inch ARP 2000 bolts, which are well-known for their strength and reliability under high loads. The assembly also includes forged 4032 Mahle pistons with a -5cc flat top design and a 4.165-inch bore size. These pistons are paired with plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing. To top it off, King XP rod and main bearings are included, offering robust lubrication and wear resistance for demanding use.
This rotating assembly is a well-built package for competition engines. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's recommended to consult with your engine builder or refer to manufacturer specifications for proper installation procedures and any additional components required for your specific build.
