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

Manley Performance has a solid reputation for building tough engine parts that hold up under pressure. If you're building a Small Block Chevy and need a strong foundation, this 355 cubic inch rotating assembly is a well-built option. It's designed for builds where you need more than stock, with a 3.480-inch stroke to increase displacement and potential power.

At the heart of this assembly is a lightweight 4340 forged steel crankshaft, chosen for its strength and ability to handle higher RPMs and increased stress compared to cast cranks. Paired with that are 4340 forged steel H-beam connecting rods. These rods are strong and come ready for 7/16? ARP 8740 cap screws, but you can opt for ARP 2000 screws for even more strength if your build demands it. The pistons are 2618 forged aluminum from Manley's Platinum Series, known for their durability and heat resistance, and they include premium chrome moly wrist pins.

This assembly is rated for up to 750 horsepower with the standard ARP 8740 bolts, and can handle up to 1,500 horsepower if you upgrade to the optional ARP 2000 cap screws. Keep in mind this assembly is not CARB approved and cannot be shipped to California. It's a serious piece for a serious engine build.
