The baseline stock 292 will make 300 ft.lbs. of torque below 2000 RPM. Anything you do to increase performance raises that torque number farther into the RPM range, defeating the purpose you are describing what your objective is. I'd keep modifications to a minimum, like a good ignition system, good breathing exhaust with maybe a good set of shorty headers or cast iron manifolds. Modifications like cams and intake/carb are tricky because you teter on a fine line of raising the RPM range higher than your objective.
