Eagle Chevy 427/454 3.766in Crank 6.135in H-Beam 41cc Dome 4.320in Pistons Rotating Assembly

This Eagle Competition Rotating Assembly is built for serious performance, especially if you're planning on using nitrous or forced induction in your Chevy 427 or 454 engine. What you get in this kit is a complete package to rebuild the heart of your engine. It includes a 3.766-inch forged 4340 crankshaft, a set of 6.135-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts, and ICON 4.320-inch forged 4032 pistons featuring a 41cc dome. To finish it off, you'll find plasma-moly file-fit piston rings and King XP rod and main bearings.

The forged 4340 steel crankshaft is a strong foundation, designed to handle the stresses of high-RPM operation and increased cylinder pressures. The H-beam connecting rods are well-known for their strength and rigidity, making them a popular choice for demanding applications, and the ARP bolts ensure they stay securely fastened. The ICON pistons are forged from 4032 aluminum, which offers a good balance of strength and thermal expansion characteristics, and the 41cc dome is designed to work with specific compression ratios. The plasma-moly file-fit rings allow for precise gapping to match your engine's bore and intended use, which is crucial for proper sealing and performance. King XP bearings are included to ensure smooth rotation and proper oil clearance for the crankshaft and connecting rods.

This assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. It's a comprehensive package for anyone looking to build a powerful and reliable engine for racing or high-performance street applications.
