The Chevrolet Performance HT383E crate engine is an exciting extension of their "High Torque" line that's designed for 1996-99 full-size GM trucks and SUVs. The HT383E is a direct replacement for your high-mileage 5.7L stock engine. 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!
