What should the clearance be between the crank trigger and the pickup?

The air-gap between the trigger wheel and the non-magnetic pickup is important to the operation of the crank trigger system, however its adjustment does not affect engine power or performance.

The proper air-gap will result in a good trigger signal at cranking rpm through high rpm with no interference to the wheel. The optimum setting is generally between 0.050" 0.080".

Eric is right about the air gap. It is 0.050" to 0.080". Keep in mind that the MSD Crank Trigger is Magnet. You will want to back up the magnet pick up as far as you can without causing the engine to quite running. By doing this, it will help clean the trigger signal.
