About this part

Product Details

This Eagle Competition Rotating Assembly gives you a solid foundation for a high-performance Chevy 350 build. You get a forged 4340 crankshaft with a 3.480-inch stroke, a set of 6.000-inch H-beam connecting rods featuring 7/16-inch ARP 8740 bolts, and a set of Mahle -5cc flat-top pistons sized for a 4.030-inch bore. It also includes plasma-moly file-fit piston rings and King XP rod and main bearings to get your engine rotating smoothly.

Eagle designed this assembly for serious racing applications, including those using nitrous oxide or forced induction. The forged 4340 crank and H-beam rods are built to handle the extra stress these power adders can create. The Mahle pistons are made from 4032 aluminum, which offers a good balance of strength and thermal expansion for performance builds. The included ARP bolts are well-known for their reliability in high-stress situations. The plasma-moly rings are designed to be file-fit, allowing for precise gap setting to match your specific engine build and tune, which is crucial for optimal sealing and performance, especially under boost or with nitrous.

This assembly is a significant step up from stock components and is intended for builders who are looking to push the limits of their Chevy 350. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions for proper assembly and balancing procedures to ensure the longevity and performance of your engine.
