Manley Rotating Assembly, SBC 355 3.480 STROKE/-4cc FLAT

Manley Performance has a long-standing reputation for building robust engine components that stand up to serious use. This rotating assembly is designed for the Chevrolet Small Block engine, specifically for a 355 cubic inch displacement with a 3.480-inch stroke and -4cc flat-top pistons. If you're rebuilding the heart of your engine and need a solid foundation, this package brings together key components that work in harmony.

At the core of this assembly is a lightweight 4340 forged steel crankshaft, chosen for its strength and ability to handle high RPMs. Paired with this are 4340 forged steel H-beam connecting rods. These rods come standard with 7/16-inch ARP 8740 cap screws, a well-known fastener for reliability, but you can opt for ARP 2000 cap screws for even greater strength. The pistons are Manley's 2618 forged aluminum Platinum Series, known for their durability and thermal stability, and they include premium chrome moly wrist pins. This combination is built to handle significant power, rated for up to 750 horsepower with the standard ARP 8740 fasteners, and an impressive 1,500 horsepower when you upgrade to the ARP 2000 cap screws.

This rotating assembly is a significant step up from stock components, offering the strength and precision needed for performance builds. Please note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations.
