Eagle Chevy 427 3.766in Crank 6.135in H-Beam 41cc Dome 4.280in Pistons Balanced Assembly

This is the Eagle B68311030 balanced rotating assembly, built for Chevy 427ci engines. It's a well-built package designed for naturally-aspirated racing applications, offering a solid foundation for a performance build. If you're looking to put together a powerful street or strip engine, a balanced rotating assembly like this takes a lot of the guesswork and machine work out of the equation.

At the heart of this assembly is a forged 4340 steel crankshaft with a 3.766-inch stroke. Paired with it are 6.135-inch H-beam connecting rods, known for their strength and reliability under stress. These rods use 7/16-inch ARP 8740 bolts, a popular choice for their durability. The pistons are forged 4032 aluminum from Icon, featuring a 4.280-inch bore and a 41cc dome, which helps achieve a specific compression ratio depending on your cylinder heads. This assembly also includes plasma-moly file-fit piston rings and King XP rod and main bearings, all balanced as a complete unit to reduce engine vibration and improve overall performance.

Because this assembly is balanced, it's ready to be installed into your engine block with less internal balancing work required at the machine shop. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and any additional components needed for your specific engine build.
