Got a hard starting and somewhat poor running 302 (1973). I suspect a carb rebuid is in order but I haven't checked fuel pressure yet and I figured new plugs and points wouldn't hurt regardless. Much to my joy when I pulled the cap I found a Pertronix (coupled with an Accel SuperCoil). My Haynes manual shows the correct gap for a '73 302 to be 0.035, but I pulled one plug to examine and found 0.045 (which, strangely, is the correct gap for the same plug on a '74).
My questions: does the gap change with a Pertronix or were my plugs just gapped incorrectly by whomever installed them? Why would the exact same plug have a significantly different gap target on a '74 (that was still a point distributor wasn't it)?
Thanks
