    I have a 12.1 compression ratio with the digital 6 plus msd ignition, msd ready to run distributor, and msd wires. What is the proper gap on the plugs. the car has nitrous on it.

    The Gap

    Run .035" on the plugs. You can try .040 if your coil is hot enough. I ran .040" on my plug with no problems with my compressions at 11.66. They recommend .028"-.035" with nitrous but is a "safe" recommendation.
