About this part

Product Details

Starting with a 3.750-inch cast crankshaft, this Eagle rotating assembly is built for your Chevy 350. It’s designed for street vehicles running on pump gas and naturally aspirated setups, making it a solid choice for a rebuild or performance upgrade. The assembly includes 5.700-inch I-beam connecting rods, which are a well-known workhorse for many engine builds. These rods are secured with 3/8-inch ARP 8740 bolts, a name you can trust for reliable clamping force under stress.

The pistons are Hypereutectic KB Claimer flat-tops, measuring 4.000 inches in bore diameter, and feature a -5cc dish to help achieve a desired compression ratio. They come fitted with plasma-moly standard gap rings, which help with sealing and oil control. For the bottom end, King SI rod and main bearings are included, offering good durability for street use. This assembly is internally balanced and comes with a 153-tooth flexplate, simplifying installation for engines using that tooth count.

This balanced rotating assembly is a key component for anyone rebuilding or significantly upgrading their Chevy 350 engine. It’s important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications.
