Eagle Chevrolet Big Block +.030 Bore Competition Rotating Assembly Kit

This is the Eagle Chevrolet Big Block +.030 Bore Competition Rotating Assembly Kit, designed for serious performance builds in Chevy 454 engines. If you're looking to put together a powerful engine for racing, especially with nitrous or forced induction, this kit gives you the core components to build a strong rotating assembly.

At the heart of this kit is a 4.250-inch forged 4340 steel crankshaft, a robust foundation for high-RPM operation. Paired with it are 6.385-inch H-beam connecting rods, known for their strength and reliability under stress. These rods are secured with 7/16-inch ARP 8740 bolts, a name you can trust for high-performance engine builds. The pistons are forged 4032 aluminum flat tops from Mahle, measuring 4.280 inches in diameter with a -3cc dish, designed to work with the crank and rods for a precise +.030 inch overbore. You also get plasma-moly file-fit piston rings, allowing for custom ring gap setup to match your specific engine build and intended use. Finally, the kit includes King XP rod and main bearings, offering excellent durability and performance for demanding applications.

This assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. It's a well-built package for anyone serious about maximizing the performance of their Chevy Big Block.
