Got a pre-1980 GM truck with a tired Small-Block? Forget the rebuild or reconditioned used engine and take your trusty truck’s capability to the next level with our big-torque HT383 stroker crate engine.
Its extra displacement and unique parts are designed to build a wide, flat torque curve you simply won’t get with a stock-type rebuild.
The HT383 features a brand-new engine block with four-bolt mains — an upgrade for most production engines that came with two-bolt mains — along with a forged-steel crankshaft and a smooth hydraulic roller camshaft. Its 9.1:1 compression ratio allows it to run on regular unleaded gasoline, too.
We deliver the HT383 with an aluminum intake manifold, ready for you to swap over the accessories from your tired engine. It’s also backed by a 24-month/50,000-mile (80,000 km) limited warranty*.
*Whichever comes first. See dealer for warranty details.
Connect & Cruise Crate Powertrain Systems provide factory-matched engine-and-transmission combinations that include specially calibrated controllers and wire harnesses designed for retrofit installations in older vehicles.
