    Depend's on what ignition you are running, stock or hei type the gap should be 35, mag will be tighter at about 20 or so.

    antrant, hei, is an ignition that has the coil built into the distributor, similar to your mallory in performance but not widely used in racing applications, the mallory you have is one I have used and still do on my lake boats, the plug gap I used for this ignition is .035, be sure to check the manufaturers instructions to see if a ballast resistor is required, because if it does and you don't have one you can destroy the module in your distributor, replacements are kind of pricey.
