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

What you get in this kit is a complete rotating assembly for your Small Block Chevy engine, built to handle serious power. It includes a lightweight 4340 forged steel crankshaft, Manley's Pro Series Lightweight I-Beam connecting rods fitted with 7/16? ARP 2000 cap screws, and 2618 forged aluminum Platinum Series pistons complete with Premium Chrome Moly wrist pins. This is a well-built package designed for builders looking to push their engine's limits.

The heart of this assembly is the 4340 forged steel crankshaft, chosen for its strength and lighter weight compared to cast iron. Paired with the Pro Series I-Beam rods, which are also designed to be lightweight yet strong, this setup helps reduce reciprocating mass. This can lead to improved engine response and durability under high RPM conditions. The Platinum Series pistons are forged from 2618 aluminum, a material known for its toughness and ability to withstand high temperatures and pressures, making them a solid choice for performance builds. The included Premium Chrome Moly wrist pins are a strong link between the piston and rod.

This Manley rotating assembly is rated for up to 750 horsepower when using the included ARP 8740 cap screws, and can handle an impressive 1,500 horsepower if you opt for the upgrade to ARP 2000 cap screws. Please note 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 balancing procedures.
