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

Eagle is well-known for making robust engine components, and this Pro Street rotating assembly is a prime example of their work for Chevy 400 engines. If you're building a naturally-aspirated racing engine, this assembly is designed to handle the demands of that kind of use. It brings together all the core rotating parts you'll need to get your engine internals squared away.

At the heart of this assembly is a 3.750-inch forged 4340 crankshaft, chosen for its strength and durability under high stress. Paired with it are 6.000-inch I-beam connecting rods, also made from strong 4340 material, and they come equipped with 7/16-inch ARP 8740 bolts to ensure a solid connection. The pistons are forged 4032 Icon flat-tops with a -5cc dish, designed for a 4.165-inch bore, and they include plasma-moly file-fit rings. To top it off, this kit comes with King XP rod and main bearings, known for their performance and reliability.

This assembly is intended for naturally-aspirated racing applications. Please note that this part is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
