    spark plug gap and ignition timing?

    Changed plugs on my LS1
    Under hood sticker, sp gap = 0.060
    If I gap plugs @ 0.040 would the less distance cause the plug to fire slightly earlier thereby advancing ignition timing?
    Any thoughts?

    Thanks

    the computer and ignition control module tell the coil when to fire boss. a shorter gap will only give you a smaller distance spark and have less chance for spark "blowout" a non issue on a n/a engine.
