Eagle Chevrolet 427 4.125in Bore 4.000in Stroke -20CC Rotating Assembly Kit

When you're building a serious performance engine, especially one intended for racing, nitrous, or forced induction, the rotating assembly is the heart of it all. This Eagle Chevrolet 427 rotating assembly kit gives you the core components to build a strong foundation. You're getting a 4.000-inch stroke forged 4340 crankshaft, which is a solid piece for handling the stresses of high-RPM operation and increased cylinder pressures. It's paired with 6.000-inch H-beam connecting rods that are specifically clearanced for stroker applications and come with 7/16-inch ARP 2000 bolts, known for their strength and reliability in demanding builds.

The kit also includes forged 4032 aluminum pistons with an inverted dome design, creating a -20cc volume to achieve a specific compression ratio when paired with your cylinder heads. These pistons are designed for a 4.125-inch bore. You'll also find plasma-moly file-fit piston rings, giving you the flexibility to set your ring gaps precisely for your engine's needs, which is crucial for sealing and performance. To top it off, the assembly comes with King XP series rod and main bearings, offering robust protection for your crankshaft and connecting rods under heavy load.

This assembly is designed to fit engines with Chevy 400 or 350 mains. Keep in mind that this kit is not CARB approved and cannot be shipped to California. It's a well-built package for those looking to push the limits of their engine.
