Extra cubic inches deliver greater torque for your truck
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 that hits the 400-lb-ft mark by 2500 rpm and doesn’t dip below it through the 4000-rpm peak (435 lb-ft). It also makes 340 horsepower. That’s power and torque 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.†
