Eagle Chevy 400 3.750in Crank 5.700in I-Beam Rods -16cc 4.185in Pistons Rotating Assembly

If you're building a Chevy 400 engine for naturally-aspirated racing, this Eagle Pro Street rotating assembly is a solid foundation. It bundles together the key components you need to get your short block started, all designed to handle the demands of the track.

At the heart of this assembly is a 3.750-inch forged 4340 crankshaft, known for its strength and durability. Paired with it are 5.700-inch 4340 I-beam connecting rods, which are secured with 7/16-inch ARP 8740 bolts. These ARP bolts are a popular choice for their reliability in high-stress applications. The kit also includes 4.185-inch forged 4032 pistons featuring an inverted dome design with a -16cc volume, suitable for specific compression ratio targets. You'll also find plasma-moly file-fit piston rings, allowing for precise gap adjustment, and King XP rod and main bearings to ensure smooth rotation and proper oil clearance.

This assembly is intended for racing use and is not CARB approved, meaning it cannot be shipped to California. It's a well-built package that provides the essential rotating components for a performance-oriented Chevy 400 build.
