Eagle Chevy 454 Tall Deck 4.500in Crank 6.660in H-Beam 43cc Dome 4.280in Pistons Balanced Assembly

Starting with a forged 4340 steel crankshaft with a 4.500-inch stroke, this balanced rotating assembly from Eagle is built for serious performance, especially in tall deck Chevy 454 applications. This assembly is designed to handle the demands of racing, including the stresses of nitrous and forced induction setups. The robust construction means it's ready for whatever you throw at it under the hood.

The assembly includes 6.660-inch long H-beam connecting rods, which are known for their strength and ability to withstand high RPMs and significant cylinder pressures. These rods are secured with 7/16-inch ARP 8740 bolts, a name you can trust for reliable fastening in high-stress environments. For the pistons, Eagle has chosen Mahle forged 4032 aluminum pistons with a 43cc dome volume, designed to work with the 4.500-inch stroke crank to achieve a specific compression ratio. These pistons come with plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing. To top it off, King XP series rod and main bearings are included, offering excellent durability and reduced friction for smooth operation.

This balanced assembly means the crankshaft, connecting rods, pistons, rings, and bearings have been precisely weighted and balanced as a unit. This is crucial for reducing vibration and ensuring the longevity of your engine, especially at higher RPMs. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's a solid choice for anyone rebuilding or building a high-performance 454 engine that needs a strong foundation.
