Eagle Chevy 400 3.750in Crank 6.000in I-Beam Rods -5cc Flat Top 4.165in Pistons Rotating Assembly

Eagle has a solid reputation for making well-built engine components, and this Street & Strip rotating assembly is a prime example. If you're building a Chevy 400 engine for street use with pump gas and no forced induction, this assembly is designed to get you going. It's a complete package that brings together the core rotating parts you need to get your engine turning.

At the heart of this assembly is a 3.750-inch cast crankshaft, paired with 6.000-inch I-beam connecting rods. These rods come equipped with 3/8-inch ARP 8740 bolts, a strong choice that ensures reliable performance under normal street driving conditions. The pistons are forged 4032 aluminum from Mahle, featuring a -5cc flat top design and a 4.165-inch bore size, which are common specs for many Chevy 400 builds. This assembly also includes plasma-moly standard gap rings and King rod and main bearings, so you're getting a well-rounded set of components ready for installation.

This rotating assembly is a great starting point for a naturally aspirated street engine. Remember that this kit 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.
