Eagle Chevy 400 3.750in Crank 6.125in H-Beam 6.2cc Dome 4.155in Pistons Rotating Assembly

This Eagle Competition Rotating Assembly gives you a complete, well-built package for your Chevy 400 engine build. You get a forged 4340 crankshaft with a 3.750-inch stroke, a set of 6.125-inch H-beam connecting rods secured with 7/16-inch ARP 2000 bolts, and forged 2618 JE pistons featuring a 6.2cc dome and a 4.155-inch bore. It also includes plasma-moly file-fit piston rings and King XP rod and main bearings to get your engine rotating smoothly.

This assembly is specifically put together for demanding racing applications, including those using nitrous oxide or forced induction. The forged 4340 crank and H-beam rods are strong choices for handling the extra stress these power adders can create. The JE pistons are designed for high performance, and the included King XP bearings are known for their durability under load. The file-fit rings allow for precise setup during engine assembly, ensuring a good seal.

When assembling this rotating assembly, pay close attention to the file-fit nature of the piston rings; proper gapping is crucial for performance and engine longevity. This kit is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. Always consult your engine builder or the manufacturer's detailed instructions for precise assembly procedures and specifications.
