Eagle Chevy 454 Tall Deck 4.500in Crank 6.660in H-Beam 43cc Dome 4.310in Pistons Balanced Assembly

If you're building a serious performance Chevy 454 tall deck engine, especially one intended for racing applications like drag strip or street/strip use, a balanced rotating assembly is a critical starting point. This Eagle Competition Rotating Assembly is designed to handle the demands of high-horsepower builds, including those using nitrous oxide or forced induction. It provides a solid foundation for your engine project, ensuring all the major rotating components are matched and balanced from the start.

This assembly features a forged 4340 steel crankshaft with a 4.500-inch stroke, paired with strong 6.660-inch H-beam connecting rods. These rods are secured with robust 7/16-inch ARP 8740 bolts, known for their reliability under stress. The pistons are forged 4032 aluminum from Mahle, featuring a 43cc dome and a 4.310-inch bore size, which are crucial for achieving specific compression ratios. The assembly also includes plasma-moly file-fit piston rings, allowing for precise ring gap adjustment to match your engine's bore and intended use, and King XP rod and main bearings to ensure smooth operation and durability.

Having the rotating assembly balanced from the factory saves you significant time and ensures the critical internal components are properly weighted. This reduces engine vibration and allows the engine to rev more freely and safely. Please note that this assembly is not CARB approved and cannot be shipped to California. Always consult with your engine builder or refer to manufacturer instructions for proper installation and break-in procedures.
