Eagle Oldsmobile 455 4.500in Crank 7.100in H-Beam Forged 4032 -15cc 4.155in Piston Rotating Assembly

This Eagle Street & Strip rotating assembly is a well-built package for your Oldsmobile 455 engine build. You get a 4.500" cast crankshaft, 7.100" H-beam connecting rods with 7/16" ARP 8740 bolts, forged 4032 Diamond pistons with a -15cc inverted dome, plasma-moly file-fit rings, and King rod and main bearings. This assembly is designed for pump gas, naturally aspirated street applications, offering a solid foundation for your project.

The 4032 forged pistons are a good choice for street performance, offering better thermal expansion characteristics than 2618 forgings, which can lead to quieter operation and improved piston-to-wall clearance. The H-beam connecting rods are strong and reliable for street use, and the inclusion of ARP 8740 bolts means you have robust hardware for the rod assembly. The cast crankshaft is a durable option for naturally aspirated builds, and the King bearings are well-known for their quality and performance in a wide range of engine builds. This assembly is a popular choice for those looking to rebuild or upgrade their Oldsmobile 455 for street driving.

Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's always a good idea to consult with your engine builder or refer to Eagle's specific installation guidelines to ensure proper assembly and break-in procedures for optimal performance and longevity.
