About this part

Product Details

If you're building a high-performance Small Block Chevy engine and need a solid foundation, a Manley rotating assembly is a smart choice. This particular assembly is designed for a 355 cubic inch displacement with a 3.480-inch stroke, featuring flat-top pistons with a -4cc dish. It's the kind of setup that lets you push the limits of your engine, whether for street performance or track use.

At the heart of this assembly is a Manley 4340 forged steel crankshaft, chosen for its strength and reliability under demanding conditions. Paired with that are Manley's 4340 forged steel H-beam connecting rods. These rods come standard with 7/16? ARP 8740 cap screws, a well-known fastener for its strength, capable of handling up to 750 horsepower. If your build aims even higher, you can opt for ARP 2000 cap screws, which can support up to 1,500 horsepower. The pistons are Manley's Platinum Series, made from 2618 forged aluminum for a good balance of strength and light weight, and they include Premium Chrome Moly wrist pins for durability.

This assembly is a serious upgrade for anyone looking to build a powerful engine. Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and balancing procedures.
