Eagle Chevy 400 3.750in Crank 6.000in H-Beam 4cc Dome 4.125in Pistons Balanced Assembly

Starting with a forged 4340 steel crankshaft featuring a 3.750-inch stroke, this balanced rotating assembly from Eagle is built for serious performance. It's designed to handle the demands of racing, including applications using nitrous oxide or forced induction. The assembly includes 6.000-inch H-beam connecting rods, known for their strength and reliability under high stress. These rods are secured with 7/16-inch ARP 8740 bolts, a popular choice for their durability and consistent clamping force.

The pistons are forged 2618 aluminum from Mahle, featuring a 4cc dome and a 4.125-inch bore size. This dome design is often used to achieve specific compression ratios when paired with the right cylinder heads. The assembly comes complete with plasma-moly file-fit piston rings, allowing for precise gap setting to match your engine's bore and intended use. King XP series rod and main bearings are included, offering robust performance and wear resistance for the critical rotating components.

This balanced assembly is ready to be installed into a Chevy 400 engine block. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
