About this part

Product Details

If you're building a high-performance Chevy 454 engine for serious racing, a balanced rotating assembly is the foundation you need. This assembly from Eagle is designed to handle the demands of competition, including nitrous and forced induction setups. It takes the guesswork out of matching critical components like the crankshaft, connecting rods, pistons, rings, and bearings, ensuring they work together harmoniously for optimal power and durability.

At the heart of this assembly is a forged 4340 steel crankshaft with a 4.250-inch stroke, providing the displacement boost for your 454. Paired with it are strong 6.385-inch H-beam connecting rods, known for their robust design and ability to withstand high loads. These rods come with 7/16-inch ARP 8740 bolts, a popular choice for their reliability in demanding applications. The pistons are forged 4032 aluminum with an 18cc dome, designed to work with specific compression ratios, and they include plasma-moly file-fit rings, which allow for precise gap setting to match your engine's bore and intended use.

To ensure smooth operation and longevity, this assembly includes King XP rod and main bearings. These bearings are well-regarded for their performance in high-stress environments. Everything in this assembly is balanced as a complete unit, which is crucial for reducing vibration and wear on other engine components, especially at higher RPMs. Please note that this assembly is not CARB approved and cannot be shipped to California.
