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

This Manley Performance rotating assembly is built for Small Block Chevy (SBC) engines aiming for a 434 cubic inch displacement with a 4.000-inch stroke and a +4cc dome piston. It’s a well-built package designed for builders who want a strong foundation for a high-performance engine build.

At its core is a lightweight 4340 forged steel crankshaft, chosen for its strength and ability to handle significant stress. Paired with this are 4340 forged steel H-beam connecting rods. These rods come standard with 7/16? ARP 8740 cap screws, a solid choice for many builds. For those pushing the limits, there's an option to upgrade to ARP 2000 cap screws, which significantly increases the horsepower capacity of the assembly.

The pistons are Manley's 2618 forged aluminum Platinum Series, featuring Premium Chrome Moly wrist pins. These pistons are designed to work with the 4.000-inch stroke and the +4cc dome volume, contributing to the overall displacement and compression ratio of your build. With the standard ARP 8740 bolts, this assembly is rated for up to 750 horsepower. Opting for the ARP 2000 cap screws raises that capability to an impressive 1,500 horsepower, making it suitable for very powerful street or race engines.

Please note that this assembly is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
