Eagle Chevy 454 4.000in Crank 6.135in I-Beam Rods Closed Chamber 4.320in Pistons Rotating Assembly

If you're rebuilding the heart of your Chevy 454 for serious naturally-aspirated racing, this Eagle Pro Street rotating assembly is a solid choice. It bundles together the critical rotating components you need to get your engine back to peak performance, specifically tuned for racing applications where every bit of power counts. This assembly is designed to handle the demands of high-RPM operation and deliver consistent power on the track.

At the core of this assembly is a 4.000-inch forged 4340 steel crankshaft, known for its strength and durability under stress. Paired with this are 6.135-inch 4340 steel I-beam connecting rods, which are a popular choice for their balance of strength and weight. These rods come equipped with 7/16-inch ARP 8740 bolts, a well-known name for reliable fastener performance, ensuring a secure connection under extreme loads. The pistons are forged 4032 aluminum from ICON, featuring an 18.3cc closed chamber dome design and a 4.320-inch bore size. These pistons are designed to work with the included plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing. To complete the package, King XP rod and main bearings are included, offering robust lubrication and wear protection for these high-performance components.

This assembly is intended for racing use and is not CARB approved, meaning it cannot be shipped to California. It's important to note that while this kit provides the core rotating assembly, you'll need to ensure all other supporting engine components are compatible and in good condition for a successful build. Proper balancing of the entire rotating assembly is also a critical step during installation to ensure smooth operation and longevity.
