Eagle Chevy 400 3.750in Crank 6.000in H-Beam -16cc 4.155in Pistons Rotating Assembly

This Eagle Competition Rotating Assembly gives you the core components to build a strong Chevy 400 engine, ready for serious performance. You get a forged 4340 crankshaft with a 3.750-inch stroke, a set of 6.000-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts, and DSS forged 4032 pistons featuring an inverted dome design with a -16cc volume. This assembly also includes plasma-moly file-fit piston rings and King XP rod and main bearings to ensure smooth operation.

Eagle designed this rotating assembly for demanding applications, including racing use with nitrous or forced induction. The forged 4340 steel crankshaft and H-beam connecting rods are built to handle significant stress, making them a solid choice for high-performance builds. The 4032 forged pistons are well-suited for these conditions, and the included file-fit rings allow for precise gap adjustment to match your specific engine build and power adder. The King XP bearings are known for their durability and performance under load.

When assembling this rotating group, pay close attention to the file-fit piston rings; proper gapping is crucial for sealing and performance, especially with boosted or nitrous applications. This assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. Always consult your engine builder or manufacturer's specifications for proper installation and tuning.
