For base timing MSD recommends a standard timing light. Keep turning the dial until the timing mark lines up with the 0-degree mark, check to see how many degrees you've dialed in on the light, and that's your total timing. If you are just interested in checking total timing over 3300 RPM, then a dial back should work, as the MSD box only provides multiple sparks under 3000 to 3300 RPM. Now, with a dial-back light, and the engine at 3000rpm, turn the dial clockwise and you'll see the timing mark on the balancer "retard" and move closer and closer to the 0-degree mark on the timing tab. Chances are your timing mark is way beyond the 12 degrees or so of your timing "tab" (the degree marker mounted to the front cover). Perfect for Sprint or drag cars without battery access, these MSD self-powered timing lights are battery-powered, which reduces the amount of wires hanging over the engine compartment. With a conventional light, in order to check total timing, you'd disconnect the vacuum advance, rev the motor to 3000rpm (that's usually fast enough to ensure the distributor timing is maxed out), and you'd pull the trigger to check timing.
