The 1960 Hawk came with two versions of the 289 V8. A 210 h.p. engine with 2 barrel carb & a 225 h.p. version with 4 barrel carb. The 210 h.p. engine had 300 lb/ft of torque and the 225 h.p. version had 305 lb/ft of torque.
The available engines that year were a 200 cubic inch 6 cylinder, a 289 cubic inch 8 cylinder, and a 302 cubic inch 8 cylinder. Assuming you meant a 289, your best bet would probably be to purchase a carb kit, rebuild the carb, and follow the instructions for adjustment. That should give you a baseline to work with.
