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

If you're building a high-performance Small Block Chevy engine and aiming for serious displacement and power, a well-matched rotating assembly is the heart of the build. This Manley Performance rotating assembly is designed to give you a solid foundation for a 434 cubic inch engine, featuring a 4.000-inch stroke crankshaft and pistons with a +4cc dome to help achieve your desired compression ratio.

At its core is a lightweight 4340 forged steel crankshaft, chosen for its strength and ability to handle high RPMs without excessive weight. Paired with this are 4340 forged steel H-beam connecting rods. These rods are well-built for durability and come standard with 7/16? ARP 8740 cap screws, a strong choice for many performance 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, known for their resilience under extreme conditions. They include premium chrome moly wrist pins, which are strong and reliable for high-stress applications. This assembly is rated for up to 750 horsepower with the standard ARP 8740 bolts, and an impressive 1,500 horsepower when equipped with the optional ARP 2000 cap screws. Please note that this assembly is not CARB approved and cannot be shipped to California.
