Manley Rotating Assembly, BBC 565 4.250 STROKE/4.600/-3cc

This Manley rotating assembly is built for serious big-block Chevrolet (BBC) builds, specifically for a 565 cubic inch displacement with a 4.250 inch stroke and 4.600 inch bore. It's a well-built package designed to handle significant power, making it a solid choice for performance engine rebuilds where durability and strength are paramount. The components are selected to work together as a balanced unit, simplifying the process of assembling a high-performance engine.

At the core of this assembly is a 4340 forged steel crankshaft, chosen for its inherent strength and ability to withstand the stresses of high RPM and significant cylinder pressures. Paired with this are 4340 forged steel H-beam connecting rods. These rods come standard with 7/16? ARP 8740 cap screws, a popular choice for many performance applications. For those pushing the limits, there's an option to upgrade to ARP 2000 cap screws, which can support even higher horsepower levels. 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 added durability.

With the standard ARP 8740 cap screws, this assembly is rated for up to 900 horsepower. If you opt for the ARP 2000 cap screws, the assembly is capable of handling up to 1,500 horsepower. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed specifications and installation guidelines to ensure proper assembly and to confirm compatibility with your specific engine block and other components.
