Chevrolet Performance 5.7L 350 HO 333 HP Turnkey Long Block Crate Engines 19433031

Unlike the base 350 Vortec in this lineup, this new Chevrolet Performance 5.7L 350 HO engine (part 19433031) is a turnkey package rated at 333 HP, with its carburetor, intake manifold, and distributor already mounted at a 9.0:1 compression ratio, ready to wire and fuel rather than built around parts you still need to source. What turnkey adds over the base engine Beyond the cast iron heads and hydraulic flat-tappet camshaft, this package bundles the carburetor, intake manifold, distributor with spark plugs and wires, a long-style water pump, a harmonic balancer, a flexplate for automatic transmissions, and an air cleaner. Only the wiring harness, computer, and supercharger are left out, since it is a carbureted system that needs no electronics. Where it fits Chevrolet Performance built this 350 HO toward hot rods and street builds that want a plug-and-play small-block, and it works with either an automatic or manual transmission once you select the matching flexplate or flywheel. Octane requirements sit in the regular 87 to 91 range, typical for a carbureted small-block of this compression. Common questions Is this engine carbureted or fuel injected? Carbureted, with the carburetor and intake already mounted. Does it need a computer to run? No, since this is a complete carbureted ignition and fuel package rather than an electronically controlled one. Is it street legal everywhere? It is not emissions-certified, so confirm local rules before putting it on the road.
