350 HO Turn-Key Crate Engine

The Chevrolet Performance 350 HO Turn-Key Crate Engine (MPN 19433031) offers a significant power upgrade, delivering 330 horsepower and 381 ft-lbs of torque. This engine is built with robust internal components, including a cast-iron block featuring 4-bolt main caps, a forged steel crankshaft, powdered metal steel connecting rods, and cast-aluminum pistons. The high-flow Vortec iron cylinder heads have 64cc chambers and 1.940-inch intake/1.500-inch exhaust valves, contributing to its performance. Key specifications include a 9.0:1 nominal compression ratio, a hydraulic flat tappet camshaft with .435 intake/.460 exhaust lift, and a 1.5:1 stamped steel rocker arm ratio. It comes as a fully assembled crate engine, ready for installation, and includes components such as the intake manifold, oil pan, timing cover, water pump, harmonic balancer, valve covers, air cleaner, and spark plugs. The engine is externally balanced and includes a 12.750-inch, 153-tooth automatic transmission flexplate; a flywheel is required for manual transmission applications. Installation notes indicate that this engine is designed for pre-1976 street vehicles or any off-road vehicle and is not intended for marine applications. Some assembly and minor engine tuning are required. A fuel line from the fuel pump to the carburetor is necessary, and while the fuel pump pressure is pre-set, a fuel pressure regulator is not required. It also recommends the use of premium fuel. Chevrolet Performance Front Accessory Drive Kits, which may include a reverse rotation water pump, are compatible.
