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

This Manley Performance rotating assembly is built for a Small Block Chevy (SBC) 383 cubic inch engine, featuring a 3.750-inch stroke and -15cc dish pistons. It’s a well-built foundation for a serious performance engine build, designed to handle significant power levels.

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. These rods come standard with 7/16? ARP 8740 cap screws, a solid choice for many performance applications. If you're aiming for the upper limits of its capability, optional ARP 2000 cap screws are available for even greater strength. The assembly also includes 2618 forged aluminum Platinum Series pistons, known for their durability and heat resistance, complete with premium chrome moly wrist pins. This combination is rated for up to 750 horsepower with the standard ARP 8740 bolts, and an impressive 1,500 horsepower when upgraded to ARP 2000 cap screws.

This rotating assembly is a significant investment for a performance engine build. It’s important to note that this part is not CARB approved and cannot be shipped to California due to emissions regulations. Ensure you consult with your engine builder to confirm all necessary components and clearances for your specific application.
