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

This is the Manley Performance SBC 355 rotating assembly, designed for Small Block Chevrolet engines. It's a complete package featuring a 3.480-inch stroke crankshaft, flat-top pistons with a -4cc dish, and robust connecting rods, all balanced and ready for your high-performance build. This assembly is the heart of your engine's power, converting the up-and-down motion of the pistons into the rotational force that drives your vehicle.

Manley has put together a solid combination here for those looking to build a serious engine. The crankshaft is forged from 4340 steel, giving it the strength needed to handle significant power. Paired with this are 4340 forged steel H-beam connecting rods. These rods come standard with 7/16-inch ARP 8740 cap screws, a popular choice for many performance builds, but you can opt for ARP 2000 fasteners for even greater strength if your build demands it. The pistons are Manley's own 2618 forged aluminum Platinum Series, known for their durability and lightweight design, and they include Premium Chrome Moly wrist pins. This entire assembly is balanced, saving you time and ensuring proper operation.

With the standard ARP 8740 fasteners, this rotating assembly is rated for up to 750 horsepower. If you opt for the ARP 2000 cap screws, that rating increases to an impressive 1,500 horsepower, making it suitable for extreme performance applications. Please note that this assembly is not CARB approved and cannot be shipped to California. It's a well-made component for anyone serious about building a powerful SBC engine.
