Eagle Chevy 400 350 Mains 3.750in Crank 6.000in H-Beam -5cc 4.125in Pistons Rotating Assembly

Starting with a 3.750-inch forged 4340 crankshaft, this Eagle rotating assembly is built for serious performance, especially in racing applications that might use nitrous or forced induction. The crankshaft is designed to work with 350 mains, making it a solid choice for Chevy 400 blocks that have been modified to accept them. This is a well-built foundation for a powerful engine build.

Complementing the crank are 6.000-inch H-beam connecting rods, known for their strength and reliability under stress. These rods come equipped with 7/16-inch ARP 8740 bolts, a name you can trust for secure and strong connections. The assembly includes forged 4032 Mahle pistons with a -5cc flat top design and a 4.125-inch bore size, paired with plasma-moly file-fit rings. This piston and ring combination is designed for efficient combustion and durability. Finally, King XP rod and main bearings are included, offering excellent wear resistance and smooth operation for the rotating assembly.

This rotating assembly is a comprehensive package for anyone looking to build a high-horsepower Chevy engine. Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and tuning to get the most out of this robust rotating assembly.
