Manley Rotating Assembly, SBC 434 4.000 STROKE/+4cc DOME

Manley Performance has a solid reputation for making well-built engine components for demanding builds. This rotating assembly is designed for a Small Block Chevy (SBC) and offers a 434 cubic inch displacement with a 4.000-inch stroke. It's a complete package that gives you the core rotating parts needed to build a serious engine.

At the heart of this assembly is a lightweight 4340 forged steel crankshaft, chosen for its strength and ability to handle high RPMs. Paired with this are 4340 forged steel H-beam connecting rods. These rods are strong enough for serious power and come ready to accept either ARP 8740 or optional ARP 2000 cap screws, allowing you to tailor the rod's strength to your horsepower goals. The kit also includes 2618 forged aluminum pistons from Manley's Platinum Series, which are known for their durability and performance. These pistons feature a +4cc dome, which helps achieve a specific compression ratio when paired with the right cylinder heads and gasket. Premium chrome moly wrist pins are included for reliable operation.

This assembly is rated for up to 750 horsepower when using the standard ARP 8740 cap screws on the connecting rods. If your build demands more, upgrading to optional ARP 2000 cap screws can support an impressive 1,500 horsepower. Please note that this assembly is not CARB approved and cannot be shipped to California. It's a robust option for builders aiming for significant power gains from their SBC engine.
