About this part

Product Details

Starting with a forged 4340 steel crankshaft featuring a 3.250-inch stroke and 2.300-inch main journals, this Eagle rotating assembly is built for serious performance. This is the core of your engine's power delivery, and Eagle has chosen robust materials to handle the demands of racing, including nitrous and forced induction applications. The crankshaft is paired with 6.000-inch H-beam connecting rods, known for their strength and reliability under high stress. These rods come equipped with 7/16-inch ARP 8740 bolts, a popular choice for their proven performance in high-horsepower builds.

Complementing the crank and rods are Icon forged 2618 aluminum pistons. These are flat-top pistons with a -4.9cc dish, designed to work with a 4.040-inch bore. They come complete with plasma-moly file-fit piston rings, allowing for precise gap setting to optimize performance and sealing. The assembly also includes King XP rod and main bearings, which are well-regarded for their durability and ability to maintain oil pressure under extreme conditions. This combination creates a well-balanced and strong rotating assembly ready for a wide range of performance builds.

This rotating assembly is intended for Chevy 327 Small Journal (SJ) applications. Please note that this assembly is not CARB approved and cannot be shipped to California. It's important to verify all component clearances and specifications for your specific engine build before installation.
