Eagle Chevy LT1 350 1Pc 3.750in Crank 6.000in H-Beam 11cc Dome 4.030in Pistons Rotating Assembly

This Eagle Competition Rotating Assembly is a complete package designed for serious engine builds, especially those intended for racing applications. What you get is a 3.750-inch forged 4340 crankshaft, a set of 6.000-inch H-beam connecting rods equipped with 7/16-inch ARP 8740 bolts, and forged 2618 Mahle pistons. These pistons feature an 11cc dome and are sized for a 4.030-inch bore. The assembly also includes plasma-moly file-fit piston rings and King XP rod and main bearings to ensure proper lubrication and wear resistance.

This rotating assembly is built for demanding use, making it a solid choice for engines that will see high RPMs, forced induction, or nitrous oxide. The forged 4340 steel crankshaft and H-beam connecting rods are known for their strength and ability to handle significant stress, which is crucial when pushing an engine beyond its stock limits. The Mahle pistons are forged from 2618 aluminum, a material chosen for its durability under high temperatures and pressures. The inclusion of ARP rod bolts signifies a commitment to robust fastening, ensuring the connecting rods stay securely attached under extreme loads. The plasma-moly file-fit rings allow for precise gapping to match your specific engine build and desired clearances, while the King XP bearings are designed for high-performance applications, offering improved durability and oil flow.

When building a high-performance LT1 engine, a well-matched rotating assembly like this one is fundamental. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Ensure you have the necessary machine work done to your block and heads to accommodate the specific dimensions of this assembly, including the 4.030-inch bore pistons and the crankshaft stroke. Proper balancing of the rotating assembly is also a critical step that should be performed by a professional machine shop before installation to ensure smooth operation and longevity.
