About this part

Product Details

If you're building a high-performance Chevy 350 engine for racing, especially with nitrous or forced induction, a balanced rotating assembly like this one from Eagle is a solid foundation. This assembly includes a forged 4340 crankshaft, H-beam connecting rods, and forged pistons, all balanced together to ensure smooth operation at high RPMs. Getting the rotating assembly balanced from the start saves you time and ensures the critical internal components work in harmony.

The heart of this assembly is the 3.750-inch stroke forged 4340 crankshaft, known for its strength and durability under demanding conditions. Paired with 5.700-inch H-beam connecting rods secured by 7/16-inch ARP 8740 bolts, this setup is built to handle significant stress. The forged 4032 aluminum pistons feature an inverted dome design with -18cc volume, designed to work with a 4.060-inch bore and achieve a specific compression ratio. They come with plasma-moly file-fit rings, giving you the flexibility to achieve a perfect seal in your cylinders. King XP rod and main bearings are included, offering robust protection for the crankshaft and connecting rod journals.

This balanced rotating assembly is a critical step for anyone looking to push their Chevy 350 engine beyond stock performance levels. Remember that this assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder or manufacturer's instructions for proper installation and break-in procedures.
