About this part

Product Details

This is a balanced rotating assembly from Eagle, built for serious performance applications like racing, nitrous, or forced induction on a Chevy 350 engine. It includes a forged 4340 crankshaft with a 3.750-inch stroke, 6.000-inch H-beam connecting rods fitted with 7/16-inch ARP 8740 bolts, and forged 4032 Icon pistons with an -18cc inverted dome, sized for a 4.060-inch bore. This assembly comes complete with plasma-moly file-fit rings and King XP rod and main bearings, all balanced and ready for installation.

The use of a forged 4340 steel crankshaft and H-beam connecting rods means these components are built to handle significant stress, making them a solid choice for engines that will see hard use. The Icon pistons are forged from 4032 aluminum, which offers a good balance of strength and thermal expansion characteristics suitable for performance builds. The included ARP bolts are well-known for their reliability in high-stress applications. This assembly is balanced from the factory, saving you a critical step and ensuring proper engine operation right out of the box.

When installing this rotating assembly, remember that the pistons come with plasma-moly file-fit rings, meaning you'll need to gap them to your specific application to ensure optimal performance and sealing. The King XP bearings are designed for demanding use, providing robust lubrication and wear resistance. Please note that this assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder or manufacturer's specifications for precise installation procedures and any additional components required for your specific build.
