SKU: 19420877

A high-torque direct replacement for 1996-99 GM full-size trucks and SUVs

 

The Chevrolet Performance HT383E crate engine is an affordable and more powerful emissions-legal* direct replacement for the tired 350 engine in your 1996-99 full-size GM truck or SUV. The larger displacement delivers up to 10 percent more horsepower and more usable torque for effortless towing. It is extra power you won’t get with a stock-type rebuild or reconditioned used engine.

 

The HT383E is designed to replace the L31 5.7-liter engine in half-ton models of the Silverado, Suburban, Tahoe, Sierra, and Yukon. You simply swap the intake manifold, throttle body, exhaust manifolds, and other accessories from your old 350 onto the HT383E and install it in your truck with no further modifications.

 

The engine uses a brand-new four-bolt main block, a forged-steel crankshaft, a smooth roller camshaft, and durable iron Vortec heads, helping it deliver the dependable power you expect from the venerable Small-Block V-8. It even comes with a new distributor, water pump, and other components that would be replaced during a rebuild.
