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

Built from 4340 forged steel, the crankshaft in this Manley rotating assembly is designed for serious performance applications. This assembly is specifically configured for a Small Block Chevrolet (SBC) engine, featuring a 3.480-inch stroke and -4cc flat-top pistons, creating a 355 cubic inch displacement. This combination is a popular choice for builders looking to extract more power from their SBC without going to a larger displacement block.

The connecting rods are also crafted from robust 4340 forged steel in an H-beam design, a strong choice for handling increased cylinder pressures. They come standard with 7/16-inch ARP 8740 cap screws, capable of supporting up to 750 horsepower. For those pushing the limits further, an optional upgrade to ARP 2000 cap screws is available, raising the horsepower ceiling to a formidable 1,500 HP. The pistons are Manley's Platinum Series, made from 2618 forged aluminum and include premium chrome moly wrist pins, ensuring durability and light weight for high-RPM operation.

This rotating assembly is a well-built foundation for a performance engine build. It’s important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed specifications and installation guidelines for proper assembly and tuning.
