    Chevrolet Performance's HT383E crate engine is an affordable and more powerful direct replacement for the tired 350 engine in your 1996-99 full-size GM truck or SUV. The larger displacement delivers up to 323 horsepower at 4,200 rpm and a whopping 444 lb.-ft. of torque. It is extra power you won't get with a stock-type rebuild or reconditioned used engine.

    Like the standard HT383, this crate engine starts with a cast-iron block with four-bolt main caps, a forged steel crankshaft, a smooth hydraulic roller camshaft and a set of iron Vortec cylinder heads. Its 9.1:1 compression ratio is perfect for regular gasoline at all altitudes and engine loads. It also includes a new distributor, water pump and other components that would need to be replaced during a rebuild.

    The HT383E is designed to replace the L31 5.7-liter engine in half-ton models of the Silverado, Suburban, Tahoe, Sierra and Yukon. Simply swap the intake manifold, throttle body, exhaust manifolds and other accessories from the original 350.
