Small-Block Crate Engines - HT383E

When it comes to breathing new life into your trusted truck, the HT383E delivers. If you are going to go off-road racing or hill-climbing with your old half-ton truck, the HT383E provides a great boost in horsepower and torque, compared to the
original small-block 350 that came from the factory.

To make the installation easy and economical, you can simply swap the intake manifold, throttle body, exhaust manifolds and other engine accessories from the original 350 engine. The engine uses a brand-new four-bolt-main iron block, a forged steel stroker crankshaft (including a 4X crankshaft position sensor), a smooth roller camshaft and durable cast-iron Vortec-style cylinder heads. It comes with a new water pump and a vibration dampener that would normally be replaced during a complete rebuild of your original engine.

Save money and enjoy increased power and torque when you choose the HT383E crate engine, designed and tested by Chevrolet Performance engineers.
