Manley Rotating Assembly, SBC 383 3.750 STROKE/-4cc FLAT

Starting with a 4340 forged steel crankshaft, this Manley rotating assembly is built for serious performance. The 3.750-inch stroke combined with the -4cc flat top pistons creates a 383 cubic inch displacement for Small Block Chevy engines. This setup is designed to handle significant power, rated for up to 750 horsepower with standard ARP 8740 cap screws, and can be pushed to 1,500 horsepower if you opt for the ARP 2000 cap screws. The 4340 forged steel H-beam connecting rods are strong and reliable, featuring 7/16-inch ARP 8740 or optional ARP 2000 cap screws for secure assembly. The included 2618 forged aluminum Platinum Series pistons are lightweight and durable, coming with premium chrome moly wrist pins for added strength.

This assembly is a well-built foundation for a performance engine build. The combination of forged steel and forged aluminum components means it's designed to withstand the stresses of higher RPMs and increased cylinder pressures. When you're aiming for a substantial horsepower increase over stock, a balanced rotating assembly like this is crucial for reliability and performance. It's important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations.
