Product Details
Eagle is well-known for building strong engine components, and this competition rotating assembly is a prime example of their work for Chevy V8s. If you're building a high-performance engine for racing, especially one that will see nitrous or forced induction, this assembly is designed to handle the extra stress. It's a complete package that gives you the core rotating parts needed to get your engine project moving forward.
At the heart of this assembly is a 3.750-inch forged 4340 crankshaft, chosen for its strength and durability under demanding conditions. Paired with it are 5.700-inch H-beam connecting rods, which are a popular choice for their robust design. These rods come equipped with 7/16-inch ARP 8740 bolts, known for their reliability in high-stress applications. The pistons are forged 4032 Icon units, featuring a -23cc inverted dome design and a 4.185-inch bore size, ready to be fitted with the included plasma-moly file-fit rings. To round out the rotating assembly, King XP rod and main bearings are included, offering solid performance and protection for these critical components.
This assembly is intended for serious performance builds and is not CARB approved, meaning it cannot be shipped to California. It's important to note that this kit includes the essential rotating components, and you will need to source other engine parts like camshafts, cylinder heads, and a block to complete your engine build. Always refer to manufacturer instructions for proper installation and break-in procedures.
