Product Details

Chevrolet Performance SP383 C.I.D EFI Long Block Crate Engines

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 hp at 4,200 rpm and a whopping 444 lbs.-ft. of torque. It's 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 heads. Its 9.1:1 compression ratio is perfect for regular gasoline at all altitudes and engine loads. It also includes a new water pump.

The HT383E is designed to replace the L31 5.7L 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. It's an emissions-legal stroker for trucks!
