Specially tuned for torque, the all new HT 383 delivers great truck power in a small block package. With its 3.80" stroke and Vortec cylinder heads the HT 383 makes awesome torque, down low where you need it for towing or four wheeling off road. Peak torque is 415 ft.lbs at 3500 rpm, but the HT 383 makes over 400 ft.lbs. from 2500 to 4000 rpm. Developed as a truck engine, with a truck grind roller cam, heavy duty forged powdered metal connecting rods, forged crankshaft and hypereutectic pistons the HT 383 is designed to be worked. 325 horsepower at 4500 rpm doesn't hurt either. The HT 383 is an ideal replacement for any 1976 and older carbureted truck engines only or off road application.
