If you're rebuilding a Chevy 350 for serious performance, like racing or boosted applications, a balanced rotating assembly is a critical starting point. This Eagle Competition Rotating Assembly is designed to handle the demands of high-RPM use, including nitrous and forced induction setups. It brings together the core components of your engine's bottom end, all balanced as a unit to ensure smooth operation and longevity under stress.

This assembly features a 3.480-inch forged 4340 crankshaft, known for its strength and durability. Paired with it are 5.700-inch H-beam connecting rods, secured with 7/16-inch ARP 8740 bolts, which are a popular choice for their reliability in high-stress environments. The pistons are forged 4032 Icon flat-tops with a -3.7cc dish, designed to work with a 4.030-inch bore and come with plasma-moly standard gap rings. To top it off, it includes King XP rod and main bearings, which are well-regarded for their performance in demanding conditions. Having these components balanced together from the start saves you time and ensures the rotating assembly is ready for installation and tuning.

It's important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. Always refer to manufacturer instructions for proper installation and any additional components required for your specific build.
