Eagle Chevy 454 4.000in Crank 6.135in H-Beam 38cc Dome 4.310in Pistons Rotating Assembly

If you're rebuilding the heart of your Chevy 454 for serious performance, a complete rotating assembly like this one from Eagle is a solid foundation. This kit bundles together the critical components that spin inside your engine's crankcase, ensuring they're balanced and built to handle significant stress. It's designed for applications where you need more than stock, whether that's for racing, heavy towing, or just a powerful street machine.

Eagle has put together a well-built package here. The crankshaft is forged from 4340 steel, which is a strong material known for its durability under high loads. Paired with that are 6.135-inch H-beam connecting rods, also forged for strength, and they come with 7/16-inch ARP 8740 bolts, a popular choice for their reliability. The pistons are forged from 2618 aluminum and feature a 38cc dome, designed to work with specific cylinder head volumes for optimal compression. This assembly also includes plasma-moly file-fit rings, which allow for precise gapping to match your engine's bore and intended use, and King XP rod and main bearings to ensure smooth operation and good oil flow.

This rotating assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. It's a comprehensive kit that brings together many of the essential, high-strength components needed for a performance engine build. You'll want to ensure you have the correct cylinder heads and other supporting components to match the compression ratio and intended power output of this assembly.
