About this part

Product Details

If you're building a high-performance Chevy 350 engine, this balanced rotating assembly from Eagle is a solid foundation. It's designed to handle the demands of racing, including nitrous and forced induction applications. This assembly includes a forged 4340 crankshaft with a 3.480-inch stroke, paired with 5.700-inch H-beam connecting rods secured by 7/16-inch ARP 8740 bolts. The pistons are forged 4032 Mahle flat tops with a -5cc dish, designed for a 4.040-inch bore, and come with plasma-moly file-fit rings. King XP rod and main bearings are also included to ensure smooth operation and durability.

This assembly is balanced from the factory, saving you a significant step and potential cost during your engine build. The use of forged components for the crankshaft and connecting rods means they are built to withstand higher stresses and temperatures compared to cast alternatives. The Mahle pistons are well-known for their strength and precise fit, and the included ARP bolts are a trusted name in high-performance engine hardware. The plasma-moly file-fit rings allow for proper sealing and can be adjusted for optimal performance in your specific application.

This rotating assembly is a complete package for those looking to build a powerful and reliable engine. Please note that this assembly is not CARB approved and cannot be shipped to California. It is also subject to California's Prop 65 warning.
