About this part

Product Details

If you're rebuilding a Chevy 454 engine for street use with pump gas and no power adders, this balanced rotating assembly from Eagle is a solid choice. It bundles together the core components you need to get your short block built, saving you time and ensuring compatibility between the crank, rods, and pistons. This assembly is specifically designed for naturally aspirated street applications, meaning it's built to handle the demands of everyday driving and occasional spirited runs on regular pump gasoline.

This balanced assembly features a 4.000-inch stroke cast crankshaft, paired with 6.135-inch I-beam connecting rods. These rods are equipped with 7/16-inch ARP 8740 bolts, a strong choice that ensures reliable clamping force under load. The pistons are forged 4032 aluminum from ICON, featuring an 18.3cc closed chamber dome design and a 4.320-inch bore size. They come with plasma-moly file-fit rings, giving you the flexibility to set your ring gap precisely for your application. To complete the rotating assembly, King SI rod and main bearings are included, known for their durability and smooth operation.

This assembly comes balanced from the factory, which is a critical step in ensuring your engine runs smoothly and lasts longer. Balancing reduces vibration and stress on the crankshaft and bearings. 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.
