Eagle Chevy 396 4.250in 4140 Steel Crank 6.385in I-Beam Rods 12cc 4.125in Pistons Rotating Assembly

This is the Eagle Pro Street rotating assembly, built for Chevy 396 engines. It's a complete package designed to give your engine a solid foundation, especially for naturally-aspirated racing applications. When you're rebuilding or upgrading your engine, the rotating assembly is at the heart of it all, converting the up-and-down motion of the pistons into the rotational force that powers your vehicle.

Inside this assembly, you'll find a forged 4140 steel crankshaft with a 4.250-inch stroke. This is paired with 6.385-inch I-beam connecting rods made from strong 4340 steel, secured with 7/16-inch ARP 8740 bolts. The pistons are forged 4032 aluminum from ICON, featuring a 12cc dome and a 4.125-inch bore, and they come with plasma-moly file-fit rings. To top it off, King XP rod and main bearings are included, offering reliable lubrication and reduced friction for the critical bearing surfaces. This combination of well-built components is designed to handle the stresses of performance use.

This assembly is a significant upgrade for anyone looking to build a powerful naturally-aspirated engine. Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
