Chevrolet Performance 350 C.I. 330 HP Long Block Crate Engine.
The Chevrolet Performance 350HO long block crate engine (19435434) delivers reliable small-block power with 330 horsepower and 381 lb.-ft. of torque in a durable, factory-style package. Built on a cast-iron 4-bolt main block, this 350 C.I. engine combines strength and affordability for street-driven builds. Iron Vortec cylinder heads with 1.94” and 1.50” valves improve airflow over earlier production heads, while the 9.0:1 compression ratio keeps the engine pump-gas friendly.
