Eagle Chevy Pro Street 454 Rotating Assembly 4140 Crankshaft w/4340 I Beam Rods & Flat Top Pistons

If you're building a performance street or naturally-aspirated race engine for your Chevy 454, a strong rotating assembly is the heart of the operation. This Eagle Pro Street rotating assembly is built to handle the demands of a serious build, providing a solid foundation for your engine's power output.

This assembly starts with a 4.000-inch stroke forged 4340 steel crankshaft, known for its strength and durability under high stress. Paired with it are 6.135-inch long 4340 I-beam connecting rods, which are also well-suited for performance applications. These rods come equipped with 7/16-inch ARP 8740 bolts, a name trusted for their reliability in high-performance engine builds. The pistons are forged 4032 SRP units with a 14cc closed chamber dome, designed for a 4.280-inch bore. They come with plasma-moly file-fit rings, allowing for precise ring gap setting during assembly. To complete the package, King XP rod and main bearings are included, offering excellent wear resistance and performance.

This rotating assembly is intended for naturally-aspirated racing use and is not CARB approved, meaning it cannot be shipped to California. It's a well-built package designed to give you confidence in your engine's internal components.
