About this part

Product Details

If you're building a high-performance Chevy LT1 350 engine, especially for racing applications, this Eagle Competition Rotating Assembly is a solid foundation. It bundles together the core components you need to get your engine's bottom end rebuilt with strong, reliable parts. This assembly is designed to handle the demands of racing, including the extra stress from nitrous or forced induction setups.

At the heart of this kit is a 3.480-inch forged 4340 crankshaft, known for its strength and durability under high loads. Paired with it are 5.700-inch H-beam connecting rods, which are a popular choice for performance builds due to their robust design. These rods come with 7/16-inch ARP 8740 bolts, a well-regarded name in high-strength fasteners, ensuring a secure connection. The pistons are forged 4032 SRP units with an inverted dome design, creating a -24cc volume to achieve a specific compression ratio with your chosen cylinder heads and bore size. They come with plasma-moly file-fit rings, allowing for precise gap setting to match your engine's needs. To complete the rotating assembly, King XP rod and main bearings are included, offering good performance and wear resistance for these critical rotating components.

This assembly is intended for a 4.060-inch bore size. Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to ensure the longevity of your new engine components.
