Eagle Chevy 454 Tall Deck 4.500in Crank 6.660in H-Beam 43cc Dome 4.350in Pistons Balanced Assembly

If you're building a serious performance Chevy 454 engine, especially for racing applications, this balanced rotating assembly from Eagle is a solid foundation. It's designed for tall deck blocks and is built to handle the demands of high-horsepower builds, including those using nitrous or forced induction. This assembly gives you the core components needed to get your engine rotating with strength and precision.

At the heart of this assembly is a forged 4.500-inch crankshaft made from 4340 steel, known for its durability under stress. Paired with it are 6.660-inch H-beam connecting rods, which are a popular choice for their strength-to-weight ratio. These rods come with 7/16-inch ARP 8740 bolts, a well-regarded fastener known for its reliability in high-stress environments. The pistons are forged 4032 aluminum from Mahle, featuring a 43cc dome and a 4.350-inch bore size, designed to work with the rest of the assembly for optimal combustion. This kit also includes plasma-moly file-fit piston rings and King XP rod and main bearings, ensuring smooth operation and longevity.

This assembly comes balanced from the factory, which is a critical step for high-performance engines to reduce vibration and ensure smooth operation at higher RPMs. Having the rotating assembly balanced as a complete unit helps ensure that all the components work together harmoniously. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
