Manley Rotating Assembly, SBC 383 3.750 STROKE/+11cc DOME

This is the Manley Performance SBC 383 rotating assembly, designed for a 3.750-inch stroke and featuring +11cc dome pistons. It's a well-built package for anyone serious about building a high-performance Small Block Chevy engine. This assembly includes a forged steel crankshaft, forged H-beam connecting rods, and forged aluminum pistons, all selected for strength and reliability under demanding conditions.

At the core of this assembly is a lightweight 4340 forged steel crankshaft, chosen for its durability and ability to handle significant power. Paired with it are 4340 forged steel H-beam connecting rods. These rods come standard with 7/16-inch ARP 8740 cap screws, a solid choice for many builds. For those pushing the limits, there's an option to upgrade to ARP 2000 cap screws, which significantly increases the horsepower range this assembly can handle. The pistons are Manley's 2618 forged aluminum Platinum Series, known for their strength and heat resistance, and they come complete with premium chrome moly wrist pins.

With the standard ARP 8740 bolts, this rotating assembly is rated for up to 750 horsepower. If you opt for the ARP 2000 cap screws, that rating jumps to an impressive 1,500 horsepower. This makes it a versatile choice for a wide range of performance applications, from street machines to serious drag racing builds. Please note that this assembly is not CARB approved and cannot be shipped to California. It's a substantial component for a serious engine build, so ensure you have the necessary supporting components and expertise for installation.
