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

This Manley rotating assembly starts with a 4340 forged steel crankshaft, chosen for its strength and ability to handle significant stress. It's designed for a 4.000-inch stroke, which is a key dimension for achieving a 434 cubic inch displacement in a Small Block Chevy (SBC) engine. This displacement, combined with the +4cc dome pistons, helps create a robust foundation for a high-performance engine build.

The connecting rods are also made from strong 4340 forged steel in an H-beam design, which offers a good balance of strength and weight. They come equipped with 7/16-inch ARP 8740 cap screws, known for their reliability. If your build demands even more, there's an option to upgrade to ARP 2000 cap screws, which can support up to 1,500 horsepower. The pistons are Manley's Platinum Series, crafted from 2618 forged aluminum and include premium chrome moly wrist pins. This combination of materials and design ensures durability and performance for engines capable of producing up to 750 horsepower with the standard ARP 8740 bolts, and up to 1,500 horsepower with the optional ARP 2000 bolts.

This assembly is intended for builders looking to maximize the potential of their SBC engine. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always consult with your engine builder to ensure this rotating assembly meets the specific requirements of your project.
