Product Details
What you get in this Eagle rotating assembly is a complete package ready to build a serious Chevy 350 engine. Inside this box, you'll find a forged 4340 steel crankshaft with a 3.750-inch stroke, a set of 6.000-inch H-beam connecting rods featuring 7/16-inch ARP 8740 bolts, Mahle forged pistons sized at 4.040 inches with a 6cc dome, plasma-moly file-fit piston rings, and King XP rod and main bearings.

The components in this kit are well-built for the demands of racing.

The Mahle pistons are forged from 2618 aluminum, known for its strength and ability to withstand high temperatures and pressures, and the 6cc dome shape is specific to certain compression ratio targets. The inclusion of ARP bolts means you're getting reliable hardware for the connecting rods, and the plasma-moly file-fit rings allow for precise gapping to match your engine's bore and intended use. King XP bearings are also included, offering robust performance for the main and rod journals.
This rotating assembly is a significant step up for anyone building a performance Chevy 350, especially for racing. Remember that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and balancing procedures, as rotating assemblies require precise balancing to the specific components used in your build.
