About this part

Product Details

Starting with a 3.480-inch cast crankshaft, this Eagle rotating assembly is built for street performance on Chevy LT1 350 engines. It’s designed for pump gas, naturally aspirated applications, making it a solid choice for street vehicles that see regular use. The assembly includes 5.700-inch I-beam connecting rods, which are a well-known design for balancing strength and weight in performance builds.

The connecting rods come equipped with 3/8-inch ARP 8740 bolts, a detail that speaks to the attention paid to critical stress points. Paired with these are hypereutectic KB pistons featuring an inverted dome design with a -12cc volume, intended to work with a 4.030-inch bore. These pistons are matched with plasma-moly file-fit rings, allowing for precise gap setting during installation to ensure optimal sealing and performance. The assembly also includes King SI rod and main bearings, providing reliable lubrication and wear protection for the crankshaft and connecting rods.

This rotating assembly is a comprehensive package for rebuilding or upgrading your Chevy LT1 350 engine. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's important to consult with your engine builder or refer to manufacturer instructions for proper installation, especially regarding the file-fit rings and bearing clearances.
