BIG TORQUE FOR YOUR TRUCK
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 crate 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 truck blocks don't have. We then fill the block with a forged steel 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 all altitudes and engine loads.
