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

Manley Performance is well-known for making strong internal engine components. This rotating assembly is a prime example, built for serious Small Block Chevy builds aiming for significant power. It includes a lightweight 4340 forged steel crankshaft, designed to handle the stresses of high RPM and increased cylinder pressures. The assembly also comes with their Pro Series Lightweight I-Beam connecting rods, which are fitted with 7/16? ARP 2000 cap screws for a solid connection between the crank and piston.

The pistons are forged from 2618 aluminum, part of Manley's Platinum Series, and come with Premium Chrome Moly wrist pins. This combination of materials and design means the pistons are built to withstand the heat and force generated in a performance engine. This rotating assembly is rated for up to 750 horsepower when using ARP 8740 cap screws, and can handle an impressive 1,500 horsepower if you opt for the ARP 2000 cap screws, giving you a clear upgrade path.

When building a high-performance engine, the rotating assembly is the heart of it all. This Manley package gives you a well-matched set of components from a trusted name, simplifying the process of sourcing critical internal parts. 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 torque specifications.
