Manley Rotating Assembly, SBC 383 3.750 STROKE/-15cc DISH

This Manley Performance rotating assembly is built for SBC 383 cubic inch engines, featuring a 3.750-inch stroke and -15cc dish pistons. It’s a well-built foundation for serious performance builds where reliability and strength are paramount. This assembly is designed to handle significant horsepower, making it a popular choice for engine builders looking to push the limits of their small-block Chevy.

At the heart of this assembly is a lightweight 4340 forged steel crankshaft, chosen for its strength and reduced rotational mass. Paired with this are 4340 forged steel H-beam connecting rods, which come standard with 7/16" ARP 8740 cap screws. For those aiming for extreme power levels, optional ARP 2000 cap screws are available, allowing this assembly to handle up to 1,500 horsepower. The pistons are Manley's Platinum Series, made from 2618 forged aluminum and include premium chrome moly wrist pins for durability under stress.

This rotating assembly is a significant upgrade for any performance engine build. The 4340 forged steel components offer a substantial increase in strength over cast alternatives, providing peace of mind for high-RPM operation and increased cylinder pressures. Remember that this assembly is not CARB approved and cannot be shipped to California. Always consult the manufacturer's specifications for proper installation and recommended components to achieve the desired horsepower rating.
