Eagle Chevy 400 3.750in Crank 5.700in I-Beam Rods -23cc 4.155in Pistons Balanced Assembly

This balanced rotating assembly from Eagle is built for performance applications, specifically for Chevy 400 engines. What you get in this package is a complete rotating assembly ready for installation. It includes a 3.750-inch forged 4340 crankshaft, 5.700-inch 4340 I-beam connecting rods fitted with 7/16-inch ARP 8740 bolts, and 4.155-inch forged 4032 Icon pistons with an inverted dome design that offers -23cc volume. The assembly also comes with plasma-moly file-fit piston rings and King XP rod and main bearings.

The use of forged 4340 steel for both the crankshaft and connecting rods means these components are well-built to handle the stresses of performance use, especially in naturally-aspirated racing setups. The Icon pistons are also forged, offering strength and durability, and the -23cc inverted dome design is specific for certain compression ratio targets. The inclusion of ARP 8740 bolts for the connecting rods is a notable detail, as these are known for their strength and reliability in high-stress applications. The plasma-moly file-fit rings allow for precise gap setting, which is crucial for optimal sealing and performance. King XP bearings are included to ensure smooth operation and durability for the main and rod journals.

This assembly is balanced from the factory, saving you a significant step in the engine building process. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions and consult with a professional engine builder to ensure proper assembly and tuning for your specific application.
