Hey Ryan, You can spin it with a screwdriver with no problem. You could also move the plug wires all over one. Only one wire to HEI unless you count the tach wire that is not neccessary to start the car. Make sure the power source is still powered up while cranking. Some power sources cut out when you engage the starter. The timing light is a good test for spark as long as you are sure your timing light works. One thing that happens with sitting engines is the coil could go bad. That is usually the first place I go with no spark. Jim
