Chevrolet Performance 350 Vortec C.I.D. 330 HP Crate Engines 19433030

This new Chevrolet Performance 350 Vortec crate engine (part 19433030) is a 5.7L small-block rated at 330 HP, built with cast iron Vortec cylinder heads and a hydraulic flat-tappet camshaft at a 9.0:1 compression ratio, aimed squarely at classic Chevy restorations and hot rod builds.

A carbureted-first long block

The oil pan, valve covers, and timing cover are bolted on, but everything downstream of the cylinder heads is left to the builder: no intake manifold, throttle body, flywheel, wiring harness, or computer comes with it, so you will source a carburetor, distributor, and intake to finish fuel and ignition; the carbureted design means no computer is needed at all.

Where this engine belongs

Chevrolet Performance aims this 350 Vortec at classic muscle cars, hot rods, and street machines originally built around a small-block V8 from roughly the 1970s through the 1990s, where swapping in Vortec-style cylinder heads is a common way to gain airflow over an original factory 350.

Common questions

Does it include a carburetor? No, you will need to add a carburetor, intake manifold, and distributor to complete the induction system. Will it bolt into an old Camaro or Chevelle project? It is a popular swap choice for GM muscle cars of that era, provided your motor mounts and accessory drive match a small-block V8. What fuel does it run on? Regular 87 to 91 octane pump gas, and it is not emissions-certified for street use, so check local rules first.
