• HT383


Got a pre-1980 GM truck with a tired Small-Block? Forget the rebuild and take your trusty truck’s capability to the
next level with our big-torque HT383 stroker engine. Its extra displacement and unique parts are designed to build
a wide, flat torque curve that maintains at least 400 lb.-ft. between 2,500 and 4,000 rpm. The 323 hp and 444 lb.-ft.
of torque is power you simply won’t get with a stock-type rebuild.

Built for true truck strength, the engine starts with a cast-iron block with four-bolt main caps – a strength-enhancing
feature most production blocks don’t have. We then fill the block with a forged steel stroker crankshaft and a
smooth hydraulic roller camshaft, then top it off with iron Vortec heads. Its 9.1:1 compression ratio is perfect for
regular gasoline at many altitudes and engine loads.

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.
