About this part

Product Details

Starting with a 3.480-inch stroke forged steel crankshaft, this Eagle rotating assembly is built for performance Chevy 350 engines. The crankshaft is paired with 5.700-inch long I-beam connecting rods, which are also forged for strength. These rods feature 3/8-inch ARP rod bolts, a solid choice for handling increased cylinder pressures and RPMs.

The assembly includes 4.000-inch bore pistons with a -21cc dish volume. This dish volume is designed to achieve a specific compression ratio when used with common 350 cylinder heads, typically resulting in a street-friendly compression around 9.5:1 to 10.5:1 depending on head chamber size. The pistons are cast aluminum, offering a good balance of weight and durability for many performance applications. This rotating assembly is a popular choice for builders looking to upgrade their Chevy 350 from its stock 3.480-inch stroke crank and 3.750-inch bore.

This kit includes the crankshaft, connecting rods with bolts, and pistons. Bearings are not included and must be purchased separately. Ensure you have the correct main and rod bearings for your specific engine block and crankshaft journal sizes. This assembly is not CARB approved and cannot be shipped to California.
