Product Details
If you're building a high-performance Chevy LT1 350 engine for serious racing, a robust rotating assembly is the heart of your build. This Eagle competition rotating assembly is designed to handle the demands of racing, including nitrous and forced induction applications. It brings together key components that work in unison to convert the power generated by combustion into rotational force for your drivetrain.
At its core is a forged 4340 steel crankshaft with a 3.750-inch stroke, providing the foundation for increased displacement and torque. Paired with this are 5.700-inch H-beam connecting rods, known for their strength and reliability under stress, secured with 7/16-inch ARP 8740 bolts. The assembly includes 4.040-inch Mahle pistons, which are forged from 4032 aluminum for excellent thermal expansion properties and feature a -5cc flat top dish. These pistons are fitted with plasma-moly file-fit rings, allowing for precise gap setting to optimize sealing and performance. To ensure smooth operation and durability, the kit comes complete with King XP rod and main bearings.
This rotating assembly is a well-built package for those pushing their LT1 350 engines to the limit. Please note that this assembly is not CARB approved and cannot be shipped to California. It's crucial to consult with your engine builder or refer to manufacturer specifications for proper installation and balancing procedures to achieve optimal results.
