Eagle Chevy LT1 350 1Pc 3.750in Crank 5.700in I-Beam Rods -16cc 4.060in Pistons Rotating Assembly

This Eagle Pro Street rotating assembly gives you the core components to rebuild or upgrade your Chevy LT1 350 engine. Inside this kit, you'll find a 3.750-inch forged 4140 crankshaft, a set of 5.700-inch 4340 I-beam connecting rods equipped with 7/16-inch ARP 8740 bolts, and 4.060-inch forged 4032 Mahle pistons. These pistons feature an inverted dome design with a -16cc volume, and the assembly includes plasma-moly file-fit rings and King XP rod and main bearings to get you started.

This assembly is built for naturally-aspirated racing applications, meaning it's designed to handle the demands of high-RPM operation without forced induction. The use of forged materials for the crankshaft, rods, and pistons indicates a strong foundation for performance builds. Forged 4140 steel is known for its durability and resistance to fatigue, while 4340 I-beam rods offer a solid balance of strength and weight for racing. The Mahle pistons are made from 4032 aluminum, which is a good choice for performance applications due to its strength and thermal expansion properties, especially when paired with the included file-fit rings that allow for precise piston-to-wall clearance.

When building an engine with this rotating assembly, pay close attention to the file-fit rings; proper installation and gapping are crucial for performance and longevity. Remember that this assembly is not CARB approved and cannot be shipped to California. Always consult the manufacturer's detailed installation instructions for specific clearances, torque specifications, and assembly procedures to ensure optimal performance and reliability for your LT1 350 build.
