what are the torque specs on a 3.4 s.f.i
you are probably refering to a rocker arm. In a pushrod motor the rocker are opens the valves. A rod rides on the camshaft and as the lobes on it come around the rod pushes up on the rocker are which does exactly that, rocks the same as the rocker on a rocking chair . The rod pushes up on the rocker which then pushes down on the valve, opening it.
