did some reading on some other threads about spark plug gap and the thoughts are mind blowing.every thing from .035 to .060,guess i'll go with .045 and see how it goes.
I didn't see if you mentioned earlier but what kind of ignition system do you have? I gapped my plugs to .045" with a Mallory CD (same as MSD) setup, it could handle a bit more but there's not a lot to be gained from more plug gap. I'd go with .040" if you have points or stock-type electronic ignition just to make sure you don't get any misfires or wear out the coil.
