The Chevrolet Performance 19433031 (also known as the 350 HO Turn-Key) is a factory-assembled, all-new Gen I small-block V8 crate engine delivering 333 horsepower @ 5,100 rpm and 381 lb-ft of torque @ 3,700 rpm. This turn-key long block comes pre-installed with high-flow Vortec-style cast-iron heads, dual-plane aluminum intake manifold, distributor, and other essentials—ready to drop in with minimal additional components (carb, fuel line, exhaust, etc.).
