Extra Cubic Inches Deliver
Greater Torque For Your Truck!
Free Shipping!
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 this 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.
The HT383 is delivered 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.
