Hmmm, interesting. Was that .008 Hot? I know that the gap will open up when hot, that is why a car might start fine cold but not start hot.
Back in the late 80s I converted my car to a Stinger Electronic Ignition kit, but I used a stock Chrysler distributor with their electronics box. The guy at Stinger handed me a .004 brass feeler gauge and told me to use that, never had a problem. Just assumed .004 was the correct size.
