Upgrade Your Small-Block’s Torque!


Ready for a replacement? Forget the rebuild and take your vehicle’s capability to the next level with our big-torque HT383 crate engine. Its extra displacement and unique parts are designed to deliver a wide, flat torque curve that maintains at least 400 lb.-ft. between 2,500 and 4,000 rpm, with peak torque of 444 lb.-ft.!

That’s serious pulling power-and power that won’t come with a stock-type rebuild. The HT383 features a brand-new engine block with four-bolt mains (a strength-enhancing upgrade for most production engines, which came with two-bolt mains) along with a forged steel crankshaft (which includes a 4X crankshaft position sensor), and more. 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.
See your dealer for complete details. The HT383 is also available as a partial engine.

  • Comes with 12.750" externally balanced 153-tooth automatic transmission flexplate. Requires externally balanced flywheel for manual transmission.
