Product Details
If you're building a high-performance Small Block Chevy engine and need a solid foundation, this Manley rotating assembly is a smart choice. It's designed around a 383 cubic inch displacement with a 3.750-inch stroke, giving you the displacement and power potential many enthusiasts are looking for. This assembly includes a robust crankshaft, strong connecting rods, and lightweight pistons, all engineered to work together for reliable performance.
At the heart of this assembly is a lightweight 4340 forged steel crankshaft, chosen for its strength and ability to handle significant power. Paired with it are 4340 forged steel H-beam connecting rods. These rods come standard with 7/16? ARP 8740 cap screws, capable of handling up to 750 horsepower. If your build pushes beyond that, you can opt for ARP 2000 cap screws for an increased horsepower range up to 1,500. The assembly is completed with 2618 forged aluminum Platinum Series pistons, which are lightweight and durable, featuring Premium Chrome Moly wrist pins for added strength. The -15cc dish in the pistons is designed to work with specific cylinder head volumes to achieve your desired compression ratio.
This rotating assembly is a significant investment in your engine's performance and durability. It's important to note that this part is not CARB approved and cannot be shipped to California. Ensure you consult with your engine builder or refer to Manley's specifications for proper installation and compatibility with other engine components to achieve your performance goals.
