Eagle Chevy 454 4.250in 4140 Steel Crank 6.385in I-Beam Rods 23cc 4.320in Pistons Rotating Assembly

This Eagle Pro Street rotating assembly gives you the core components to rebuild or upgrade the heart of your Chevy 454 engine. You'll receive a forged 4140 steel crankshaft with a 4.250-inch stroke, a set of 6.385-inch I-beam connecting rods made from strong 4340 steel and equipped with 7/16-inch ARP 8740 bolts, and a set of 4.320-inch ICON pistons. These pistons are forged from 4032 aluminum and feature a 23cc dome to help set your compression ratio. The assembly also includes plasma-moly file-fit piston rings and King XP rod and main bearings, so you have the essential pieces to get your engine back together.

Designed for naturally-aspirated racing applications, this assembly uses well-built components to handle the demands of performance use. The forged steel crank and 4340 I-beam rods are solid choices for building a reliable performance engine. The ICON pistons are a popular option for their durability and performance characteristics. The file-fit rings allow for precise gapping to match your specific engine build and desired compression ratio, while the King XP bearings are known for their robust construction and ability to handle increased loads.

When installing this rotating assembly, remember that the piston rings are file-fit, meaning they need to be gapped to your specific cylinder bore and application. This is a standard procedure for performance engine builds to ensure proper sealing and prevent piston-to-wall contact issues. It's always recommended to consult your engine builder or the manufacturer's installation guidelines for precise details on ring gapping and bearing installation to ensure the longevity and performance of your new engine components.
