An emissions-legal small-block that brings on the torque for your 1996-1999 GM truck and SUV!

The HT383E crate engine from GM Performance Parts is an exciting new extension of our "High Torque" line that is especially designed for your 1996-1999 full-sized GM pickup trucks and SUVs. The HT383E is a direct replacement for your high-mileage 5.7L stock engine

The HT383E offers you the same brute strength of our HT383: forged steel crank, 4-bolt main cast iron block, and a camshaft design for towing and hard work. With 383 cubic inches, you also get a broad torque band that peaks at 3600 rpm with horsepower peaking at 4500 rpm.

GM Performance Parts engineers designed the HT383E so that installation is as easy as possible. Simply swap your new HT383E in place of your existing 5.7L engine using your stock intake manifold, wiring harness, and fuel injection system. The stock computer adapts to the new HT383E, and you suddenly have a stump-pulling, big-inch small-block at your disposal.
