Eagle Chevy 454 4.250in Crank 6.385in H-Beam 43cc Dome 4.310in Pistons Balanced Assembly

What you get in this balanced rotating assembly is a complete package ready to build a strong Chevy 454 engine. It includes a forged 4.250-inch stroke crankshaft, 6.385-inch H-beam connecting rods with 7/16-inch ARP 8740 bolts, 4.310-inch Mahle 43cc dome pistons, plasma-moly file-fit rings, and King XP rod and main bearings. This assembly is balanced from the factory, saving you a significant step in the engine building process.

This rotating assembly is built for demanding use, including racing applications that might involve nitrous or forced induction. The forged 4340 steel crankshaft and H-beam connecting rods are known for their strength and ability to handle high stress. The Mahle pistons are forged from 2618 aluminum, a material chosen for its durability under high temperatures and pressures, and feature a 43cc dome to help achieve a desired compression ratio. The included plasma-moly file-fit rings allow for precise gapping to match your specific cylinder bore and application, and the King XP series bearings are designed for high-performance lubrication needs.

Because this assembly is balanced, it simplifies the machine shop process and helps ensure smooth operation once installed. Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and assembly procedures.
