Eagle Chevrolet Big Block 2 Pc Seal Street & Strip Rotating Assembly Kit - 4.25in Stroke 6.385in Rod

Eagle has built a solid reputation for providing well-built performance engine components, and this Street & Strip Rotating Assembly Kit is a prime example of their commitment to quality. If you're working on a Chevy Big Block, particularly a 454, and aiming for a street-friendly build that can also handle some strip action on pump gas without forced induction, this kit is designed to get you there. It's a complete package that takes the guesswork out of matching critical rotating assembly parts.

This kit centers around a 4.250-inch cast crankshaft, giving you a substantial stroke for increased displacement and torque. Paired with it are 6.385-inch I-beam connecting rods, which are secured with strong 7/16-inch ARP 8740 bolts, ensuring they can handle the stresses of operation. For the pistons, you get forged 4032 aluminum units from Mahle, featuring an 18cc dome and a 4.310-inch bore size, designed to work with plasma-moly file-fit rings. This combination is balanced from the factory, which is a crucial step for smooth engine operation and longevity. The kit also includes King rod and main bearings for reliable lubrication and a Pioneer damper and 168-tooth flexplate to complete the assembly.

When undertaking a build like this, it's important to note that this assembly is intended for naturally aspirated, pump gas street applications. It is not CARB approved, meaning it cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions and torque specifications when assembling your engine to ensure optimal performance and durability.
